Libint:- Functions to compute two body integrals

Libint library is used to evaluate the traditional (electron repulsion) and certain novel two-body matrix elements (integrals) over Cartesian Gaussian functions used in modern atomic and molecular theory. The idea of the library is to let computer write optimized code for computing such integrals. There are two primary advantages to this: much less human effort is required to write code for computing new integrals, and code can be optimized specifically for a particular computer architecture (e.g., vector processor).
Libint has been utilized to implement methods such as Hartree-Fock (HF) and Kohn-Sham density functional theory (KS DFT), second-order Moller-Plesset perturbation theory (MP2), coupled cluster singles and doubles (CCSD) method, as well as explicitly correlated R12 methods.
From the compilation notes:-
MacOS X (versions 10.1 and 10.2) seems to set stacksize limit too low for the library generators to run properly. Use unlimit to increase the limit and then proceed with compilation
On Intel Xeon and Pentium4 systems we obtain significantly higher performance with Intel C/C++ compilers. In the latest test we compared Intel C/C++ compiler (version 7.1) against GNU gcc compiler (versions 3.2 and 3.3). libint performs at least 10% better with the former compiler. The recommended compiler options are -O3 -xW -tpp7.

LiBMCS:- Clusters based on maximum common substructure

LibraryMCS clusters a set of chemical structures on a structural basis. Structures that share a common substructure are clustered together. The common substructure is identified by the clustering program, and it is always the largest one among all substructures found in the structure set. Such substructure is called the Maximum Common Substructure (MCS). No predefined fragments are applied in finding the MCS.

Ligand Scout:-

LigandScout is a software tool that allows to rapidly and transparently derive 3D pharmacophores from structural data of macromolecule/ligand complexes in a fully automated and convenient way.

LigBuilder: Build ligands for protein active sites

I recently came across a program called LigBuilder developed at the Molecular Design Laboratory, it is a multiple-purposed program written for structure-based drug design procedure. Based on the three-dimensional structure of the target protein, it can automatically build ligand molecules within the binding pocket and subsequently screen them.
To quote from the website:-
'(1) The program analyzes the binding pocket of the target protein and derives the key interaction sites. A pharmacophore model is suggested and it could be applied to 3D database searching.
(2) User can choose either growing strategy or linking strategy to develop ligand molecules.
(3) Molecules are constructed by using fragments as building blocks. Various kinds of structural manipulation are provided, such as growing, linking, and mutation. On-the-fly minimization of conformation is performed during the building-up procedure. While the target protein is kept rigid, flexibility of the ligand molecules is considered.
(4) Molecules are evolved by Genetic Algorithm. The fitness score of a molecule is evaluated by considering its chemical viability as well as binding affinity.
(5) Chemical rules for judging 'drug-likeness' are applied to screen the resultant molecules. Chemical stability, synthesis feasibility, and toxicity can also be taken into account by defining 'forbidden structure' libraries.
(6) All the input and output molecules are in popular format, i.e. protein in PDB format and ligand in Sybyl Mol2 format. The program is very easy to use and maintain.'
LigBuilder is written in ANSI C++ language and has been tested on UNIX and LINUX but not MacOSX, I've downloaded the siource and with minor modificartions got it to run under MacOSX.
For more detailed description of LigBuilder, please refer to: Wang, R.; Gao, Y.; Lai, L. 'LigBuilder: A Multiple-Purpose Program for Structure-Based Drug Design', J.Mol.Model., 2000, 6, 498-516.
Instructions for running LigBuilder under MacOSX.
Download LigBuilder
A folder called LigBuilderv1.2 will be created in 'Downloads' in that folder you should find
bin/ default working directory
pocket/ source codes of POCKET module

process/ source codes of PROCESS module
parameter/ necessary parameters
example/ test examples
manual/ user manual in HTML
fragment.mdb/ building-block fragment library
forbidden.mdb/ forbidden substructure library
toxicity.mdb/ toxic substructure library
LigBuilder has four main modules, i.e. POCKET, GROW, LINK, and PROCESS. You need to compile them respectively. You can do this by simply entering each subdirectory, i.e. 'pocket/', 'grow/', 'link/', and 'process/', and typing 'make' to run the Makefile scripts. The scripts will compile the source codes automatically and generate the executable codes. The default C++ compiler assigned in the Makefile script is SGI 'CC' compiler. To compile under MacOSX you should open the 'MakeFile' in a text editor (i used BBEdit) and modify the first line in the 'Makefile' scripts as 'CC = g++' before compiling. You need to do this in each of the POCKET, GROW, LINK, and PROCESS folders.
Now open a terminal window and cd to the LigBuilderv1.2 folder
>cd /Downloads/LigBuilderv1.2/
Now cd to each of the POCKET, GROW, LINK, and PROCESS folders in turn and run make and then copy the resulting executable to usr/local/bin, you will need the admin password.

LSD:- Logic for Structure Determination

Logic for Structure Determination (LSD) find all possible molecular structures of an organic compound that are compatible with its spectroscopic data.

Structure building relies on connectivity data found in 2D NMR spectra, without any reference to a chemical shift database. Molecular structures containing up to 50 non-hydrogen atoms were investigated by means of the LSD program.
The measurement protocol that is required by LSD includes the recording of 1D
1H and 13C as well as 2D COSY, HSQC and HMBC spectra. The status of each atom must be defined. It includes the atom symbol, the hybridization state (sp3, sp2 or sp), the number of attached hydrogen atoms, and the electric charge. This part of the data set is most often easily deduced by the user from elementary chemical shift knowledge. The status of the heteroatoms is deduced from the elemental molecular formula.
Carbon-carbon bonds are deduced from COSY and HSQC data while HMBC and HSQC data provide connectivity relationships through one or two bonds for non-hydrogen atom. The constraints imposed by atom status and 2D NMR data may be enforced by other atom neighborhood relationships. For example, it is possible to force a carbon atom to be bound only to carbon atoms. The user is responsible for such supplementary data. Contradictory constraints lead LSD to fail in the search of a solution structure.
The low resolution of HMBC and HSQC spectra in the C-13 chemical shift domain causes peak assignment ambiguities. It is possible to define groups of resonances and to assign a HMBC correlation peak to a group. This means that the correlation is caused by at least one member of the group.
The solutions may be selected using a substructure or a combination of substructures. Those violating Bredt's rule are also discarded.
The input to LSD is coded by the user as a text file, according to the instructions in the MANUAL_ENG.html document.

A program named OUTLSD reads the generated solutions and converts them into various formats: bonds lists, 2D coordinates, fancy 3D coordinates (fancy, due to the lack of stereochemical information), and SMILES chains. The 2D coordinates can be converted to Postscript drawings and to .mol (SDF) files.
Execution of the LSD program may be controlled by specific instructions for output formatting such as: single step execution, search of the biggest found fragment (for debgging purpose), report writing, verbosity level, substructure search.
Tens of structures were investigated by means of the LSD program, essentially in the field of natural product chemistry, and especially for terpenes and alkaloids.

Lumo:- Molecular Orbital Visualisation

Lumo accelerates the visualization of molecular orbitals from electronic structure calculations by harnessing the power of the graphics processing unit in modern macs. Lumo currently reads formatted checkpoint calculations from Gaussian03/09 calculations and there is preliminary support for Orca output files. Lumo was designed to speed up the slow part of looking at molecular orbitals and making molecular orbital diagrams. Lumo eliminates several steps along the process by reading in the output of programs like Gaussian, quickly visualizing the orbitals, and creating pictures of the essential orbitals in seconds.

Lumo requires Mac OS 10.6 or higher, 64-bit processor, and an OpenCL capable compute device. Lumo is routinely run on MacBook Pros and MacBook Airs. For analysis of larger systems, it is recommended to have at least 4GB of system RAM.

There is a movie of Lumo in action on the website

Millsian:- Molecular Modeling

Millsian a new approach to molecular modeling

According to Millsian theory, atoms and bonds are made up of discrete surfaces of negative charge, not probability-density clouds. This gives Millsian the ability to calculate and render the exact charge distribution profiles for molecules of any size and complexity.


Further, electrons are localized in molecules to specific regions, i.e. functional groups which act as building blocks, or independent units, in larger structures. Using two basic equations, Millsian has solved the important functional groups of chemistry, allowing molecules of arbitrary size and complexity to be modeled trivially and almost instantly on a personal computer.
To learn about how Millsian translates the underlying theory into a molecular modeling product, please consult the papers:

Of course the actual time scale of the phenomena in atomic world is pretty small, we mean you can see the computation results in REAL-TIME.
The software simulates not only translating motions but also rotational motions of atoms/molecules. Multi-atom molecules are dealt as a rigid body. So the software has a limitation coming from which High frequency vibration of the bonding is neglected. But the time integration is effectively fast by the simple model. To solve the rotational motion the simulator adopts
quaternion based rotational equation. As for the scheme for time stepping, a Leap-Frog is adopted.

Molpro is a complete system of ab initio programs for molecular electronic structure calculations, designed and maintained by H.-J. Werner and P. J. Knowles, and containing contributions from a number of other authors. As distinct from other commonly used quantum chemistry packages, the emphasis is on highly accurate computations, with extensive treatment of the electron correlation problem through the multiconfiguration-reference CI, coupled cluster and associated methods. The recently developed explicitly correlated coupled-cluster methods yield CCSD(T) results with near basis set limit accuracy already with double-ζ or triple-ζ basis sets, thus reducing the computational effort for calculations of this quality by two orders of magnitude. Using local electron correlation methods, which significantly reduce the increase of the computational cost with molecular size, accurate ab initio calculations can be performed for much larger molecules than with most other programs.

Molecular Graphics Visualisation Tool

RasMol is a program for molecular graphics visualisation originallydeveloped by Roger Sayle. This site is provided for the convenienceof users and software developers of open source versions of RasMol.In order to ensure continuing availability of source code anddocumentation most programs and documents on this siteare subject to copyright. This does not prevent you from usingthe open-source versions of RasMol, from making copies and changes,but prevents the creation of 'closed source' versionsout of the open source versions. Appropriate copyrights and licensesappear with the relevant sources and documents. SeeCopyright and NOTICEfor applicable Copyright and other Notices.

The 'Frequently Asked Questions' (FAQ) document for OpenRasMol is derived in part from two FAQs posted to the web by Eric Martz athttp://www.umass.edu/microbio/rasmol/faq.htm,one FAQ by Roger Sayle, and one by Eric Martz. The portions of theFAQs from the Martz web site are included by permission of Eric Martz.Many of the questions in thisdocument are the same or similar to those in the earlier FAQs, but someof the answers are different. If all or part of an answer is identical to given by Roger Sayle or Eric Martz, we will put that portion in quote marks and indicate the attribution by '--RS' or '--EM'.

Some of the responses to questions come from the RasMol manual.

The original RasMol manual was created by Roger Sayle. In July 1996,Dr. Margaret Wong of the Chemistry Department, Swinburne Universityof Technology, Australia, made extensive revisions to the RasMol 2.5manual to accurately reflect the operation of RasMol 2.6. Eric Martzof the University of Massachusetts made further revisions. In May1997, William McClure of Carnegie Mellon University reorganized theHTML version of the manual into multiple sections which could bedownloaded quickly and added use of frames. Portions of the 2.7.1version of the RasMol manual were derived with permission fromWilliam McClure's version using Roger Sayle's rasmol.doc for?version 2.6.4 as the primary source. Changes have been made inAugust 2000 for RasMol version 2.7.2.

The RasMol documentation was adapted for RasTop by PhilippeValadon in August 2000.

What is this document?

This document is a compilation of questions about RasMol that either have been asked with some frequency, or which the authors of this document think mightinterest people who use RasMol.

Why won't the RasWin.exe I just downloaded run?

Many web browsers try to download RasWin.exe and its help filesas if they were ordinary text files. They are all binary files.In some cases, a browser can be convinced to do a binary downloadby holding down one of the shift keys (Alt, Opt, Shift, etc.), whileclicking on the download link. If that does not work, then youwill have to download gzipped files and unpack them under Windows.Sometimes your browser will be willing to download the gzippedfiles as binary files, but if that does not work, you will have toresort to the File Tranfer Protocol (FTP) client packaged withall copies of Windows.

I get the message 'No suitable display detected!'

This is a problem on the UNIX version of RasMol caused by one oftwo potential problems. The first is that your DISPLAYenvironment variable isn't set corrrectly or that you don't havepermission to display to the X Windows server. This can bechecked by testing whether it is possible to run any other X Windows program.

The second problem is caused by a mismatch between the configured version of RasMol and the display depths available on the current X Windows server. This is most often the case when RasMol has beencompiled in 24/32bit mode (by defining THIRTYTWOBIT in either rasmol.hor Makefile). The 24/32bit mode indicates that RasMol should use3bytes/pixel (or 16 million simultaneous colours). If the currentX Windows server is unable to display this visual depth it reportsthe 'No suitable display' error. The visual depths supported by the current X Windows server can be reported by typing the 'xdpyinfo' command. To solve the problem, recompile RasMol withEIGHTBIT defined instead (i.e use one byte/pixel or 256 simultaneouscolours).

Note: that RasMol must be configured with EIGHTBIT for 1bit/pixel(monochrome) or 8bit/pixel displays, with SIXTEENBIT for 16bit/pixeldisplays and with THIRTYTWOBIT for either 24bit/pixel or 32bit/pixeldisplays.

--RS

In pactice on most UNIX systems, the fastest way to change thepixel bit depth after a 'xmkmf' has been done, is to edit thefile 'Makefile', commenting out the wrong definition (i.e. ofEIGHTBIT, SIXTEENBIT or THIRTYTWOBIT) and uncommenting theright definition. Then 'make clean' followed by 'make' shouldcorrect the problem.

Why are there such long headers on these web pages?

We regret the necessity for the long headers. They are part of the hoops wehave to jump through to keep OpenRasMol programs and RasMol 2.7 series of releases in particular available as 'open source' software.(Please see the web page on Copyrights and Notices)

Can RasMol be distributed freely, on CD-ROMs, andused freely even for commercial purposes?

Different versions of RasMol have had different rules forredistribution. The rules for the RasMol 2.7 series are intendedto allow redistribution on an 'open source' basis.The idea is to encourage distribution of RasMol and programsderived from RasMol provided source code and documentationremain available, and a few other sensible conditions areaccepted by the distributor.

Starting with RasMol release 2.7.3, RasMol may be distributedunder the GPL, one of the most popularopen source licenses.

The specific rules for all recent RasMol releases are given in the file NOTICE.

Does this mean I can't make a commercial graphics programbased on RasMol?

If what you mean by 'commercial' is that you want to distributebinary versions and keep the source code as a secret, no, you may not do that, but if what you mean by 'commercial' is that you wishto sell programs and services based on RasMol, that you certainly may do.Just remember that your new and wonderful program has to include or referenceall the original source code and documentation, including the fileNOTICE, which will allow other people to copyyour program. In other words the rules for distributing copies ofRasMol that you have taken advantage of will also apply to people whowish to make copes of your program.

A lot of people find it easy to work within this framework, but if youneed to do commerical development which does not fit the open sourcemodel, you may not make use of any substantial portion of theRasMol 2.7 series to develop your own product.

What is the relationship between RasMol, Linux and the GPL?

Rasmol for mac os xenon

RasMol 2.7 runs quite nicely under Linux. There are pre-compiled binariesof the 2.7 series to run under Linux. Starting with the RasMol 2.7.3release, RasMol may be distributed under the GPL.However, earlier RasMol 2.7 releases are not coveredby the GPL. Those RasMol 2.7 releases have their own 'GPL-like' license (RASLIC, which carefully avoidscertain issues which, until recently, would have caused problems if we had used the GPL for those releases. Those problems havenow been resolved, and we can now use the GPL.

Is RasMol 'Year 2000 (Y2K) compliant'?

RasMol 2.6 and all prior versions are fully Y2K compliant with a singlecaveat. RasMol can read and write MDL Mol and Brookhaven PDB files, whichreserve only two characters for the year in a date field. RasMol ignoresthese fields and is therefore not affected by Y2K. However programsreading MDL Mol files generated by RasMol (or any other molecular graphicsprogram) may suffer if they process the date field.
--RS

In addition, please note that we are now well past 31 December 1999, andthere has not been a single report of a Y2K-related RasMol failure.

Is RasMol 'Euro compliant'?

IT managers in the 'euro-zone' need to assure themselves thatall software they use will support the Euro by January 1, 2002.RasMol does not deal with currency, and therefore is effectively'Euro compliant'. However, most existing versions of RasMol usethe Latin-1 (ANSI), Macintosh, or MS Windows OEM characters sets,without explicit support for the Euro symbol, which might causeRasMol to be rejected in testing for 'Euro compliance' against standardsintended for financial software. If this proves to be a nuisance,please contact [email protected]

What are the definitive literature citations for RasMol?

The currently preferred literature reference to RasMol is: Roger Sayle and E. James Milner-White. 'RasMol: Biomolecular graphics for all', Trends in Biochemical Sciences (TIBS), September 1995, Vol. 20, No. 9, p. 374.
--RS

In addition the best reference for the 2.7 series is:Herbert J. Bernstein, 'Recent changes to RasMol, recombining the variants, Trends in Biochemical Sciences (TIBS), September 2000, Vol. 25, No. 9, pp. 453-455.

Where can I get more molecule co-ordinate files?

In addition to the example files that are distributed with RasMol the major source of data files for RasMol isthe Protein Data Bank operated by the Research Collaboratory forBioinformatics (see http://www.rcsb.org/pdb). This is the mainrepository for all of the world's known 3D xray-crystallography andnuclear magnetic resonance (NMR) structures of proteins and nucleicacids. Currently (September 2000) over 13,000 are available from mirrorsites throughout the world (see http://www.rcsb.org/pdb/mirrors.html

The primary archive for three dimensional structures of small moleculesis the Cambridge Crystallographic Data Centre, with over 200,000 organic andmetal organic compounds (see http://www.ccdc.cam.ac.uk). However,for many users, this resource is not available on-line.

A list of sites that hold small molecule co-ordinates (and additional proteinstructures) is Eric Martz'z 'Molecules Galore!' WWW page athttp://www.umass.edu/microbio/rasmol/whereget.htm

[This answer was derived in part from the RS response to this question. -- HJB]

Why won't RasMol 2.7 display my bond orders?

Older versions of RasMol infer bond orders from redundantCONECT records for some molecules in a psuedo-PDB format.Unfortunately, this would cause the display of incorrectbond orders for some valid PDB format files which hadredundant CONECT records for other reasons. The featurehas been disabled until a consistent and reliablealternative can be found.

How do I measure distances within RasMol?

There are two ways to measure distances between atoms in ..RasMol. The first is to use the 'set picking distance' command, to set the mouse into interactive distance measurement mode. Then by clicking on pairs of atoms, RasMol will report the distance between them on the command line. RasMol also has similar modes for 'set picking angles' and 'set pickingtorsions'. The mouse can be returned to the default mode using 'set picking ident'.

The second approach is to use distance monitors. A distance monitorin RasMol is a graphical dotted line between an arbitrary pair of atomsoptionally labelled by the distance between them. There are two waysto add a monitor to a molecule. The first is to use 'set pickingmonitors', similar to set picking distance above. Note that this willacta as a toggle and selecting the same two atoms again will remove themonitor. Monitors can also be added from the command line using themonitor command. This command takes the atom serial numbers of thetwo end-point atoms as parameters. All monitors can be turned of usingthe command 'monitors off'.

--RS

How do I select residues in a particular chain?

The method for selecting a range of residues in a particular chain .. improved in RasMol version 2.6. It can now be done using the syntax 'select 1-25:a' to select residues 1 to 25 in chain A. Similarly 'select 25:a' and 'select :a' will select just residue 25 in chain A and all of chain A, respectively.

In RasMol versions prior to v2.6, you'd have to type an atom expression of the form 'select 1-25 and **a' where the final term is a primitive expression. This primitive expression is a wildcarded formof the form 'cys37a' where the residue name and number are replaced by the wildcard '*'.

Note that care has to be made to ensure that RasMol can determine which field is being specified. For example, although 'select *a' will select all residues in chain A, if the chain identifier was a number, 'select **1' would have to be used, as 'select *1' denotesresidue 1. To avoid any ambiguity, an optional colon character is now used to prefix the chain identifier, allowing expressions such as'cys:a', 'cys35:1', '*:1' and even just ':1'.

See also the RasMol Manual.

--RS

How can I create the PDB file for a particular sequence?

May I strongly recommend that you consider using the Swiss-Modelserver, written by Manuel Peitsch at the University of Geneva. Thise-mail and WWW server accepts as input either an amino-acid sequenceor a multiple sequence alignment with a protein of known structureand performs comparative homology modelling to return the potential3D structure to you by e-mail as a PDB file.

For more information visit the Swiss-Model WWW page at www.expasy.ch/swissmod/SWISS-MODEL.html

--RS

I can't find the command line window in RasWin

This is a confusing problem with RasWin. When RasWin startsunder Microsoft Windows the command line window is initially iconised(unlike the Macintosh or UNIX versions). The 'RasMol Command Line'icon appears at the bottom of the screen on the Windows background.Unfortunately, this is often obscured by another window such as theProgram Manager or the File Manager. Both the 'RasMol' icon and the'RasMol Command Line' icons can be seen if all the open windows are minimized.

A more convenient solution is to make use of the Microsoft 'Alt-Tab'control key combination. Hold down the 'Alt'-key, and press the 'Tab' key one or more times until the name of the window you wish to bringto the front appears, then release the 'Alt'-key.

--RS

How do I create high resolution images in RasMol?

Unfortunately, raster images generated by RasMol are currently limited by the screen resolution (though this deficiency is actively being worked on).This means that images will generated at the resolution of about 72dpi(dots per inch) even though most printers (including colour printers) support resolutions of 300dpi, 450dpi or even 600dpi. This leads tojagged bitmap like printouts where the individual pixels are often visible.

The exception to the above rule is images produced in Vector Postscriptformat using the 'write vectps' command. These output files have the advanatge of being generated at the printer's resolution, but the disadvantage of not supporting all of RasMol's representations.

One way to minimise the limitations of screen resolution is to expand ormaximise the RasMol graphics window to the full size of the screen before generating an output file. This ensures that the image contains as muchdetail as possible. Another commonly used trick is post-process the imagein a graphics package such as PhotoShop or 'xv' to expand and then bluror smooth the images generated by RasMol.

..

As mentioned above RasMol's resolution limitations are currently beingremoved by four approaches:

  1. Support for high resolution output images (at x4 screen resolution).
  2. The ability to have large resolutions in UNIX command-line only mode.
  3. Vector PostScript support for all RasMol representations.
  4. Export of model file formats (including POV, Raster3D, DXF and VRML) to other rendering programs such as photo-realistic ray-tracers.

Generating RasMol animations non-interactively in UNIX

The inability to use the save and write commandsin a RasMol script file is a deliberate security feature.There was a concern about the security of using RasMol on the Internet when researchers started e-mailing and FTPing 'untrusted' script files between sites. This was especially true of sites that have configured Netscape to fire up RasMol with a RasMol script file MIME type.Such a script, executed with 'rasmol -script <filename>' may potentially overwrite system and user files, for example creating a '~/.rhosts' file on the remote machine. To defend against this threat I decided to disable the save and write command from within RasMol, unless the command 'set write true

'had been entered interactively on the command line.

The solution to the problem is to run your scripts with:ori.e. pipe the commands into stdin. RasMol can't tell that these haven'tbeen generated interactively and allows save and write commands.

--RS

Is there an Acorn Archimedes version of RasMol?

The Acorn Archimedes (ARM) version of RasMol has been ported by MartinWuerthner at the University of Stuttgart,'[email protected]'. The Archimedes distribution is available at the following sites:HENSA (difficult to reach for users from outside the UK):micros.hensa.ac.uk (in /micros/arch/riscos/e/e089/rasmol.arc),the University of Kaiserlautern (Germany):ftp.uni-kl.de (in /pub/acorn/long/science/chemistry/rasmol.arc),and the University of Stuttgart (Germany):ftp.uni-stuttgart.de (in /pub/systems/acorn/riscos/etc/rasmol110.spk).

The first RISC OS release (1.10) of RasMol has the following features inaddition to those of the X version:

  • runs on all Acorn 32-bit RISC computers under RISC OS 3.1 or higher, supports all display depths up to 24 bpp, just about runs on a 2MB machine
  • fully supports RISC OS cooperative multitasking even while rendering the image
  • Floyd-Steinberg colour dithering for 16 and 256 colour modes
  • support of both the RasMol mouse mode and a more RISC OS-like way using a tool bar with rotation/translation/slabbing etc. tools
  • extended menu structure (e.g. sub-menus to enter parameters for display options)
  • exports native RISC OS bitmap format, RISC OS drag-and-drop support

--RS

The latest release for the Acorn is the RISC OS port of RasMol 2.7.1 (RISC OS port version 1.31b) (see http://www.mw-software.com/software/rasmol/rasmol.html).

Is there an MacOS X version of RasMol?

The short answer is yes -- see the sourceforge openrasmol site.

Why can't I see my data files in Classic under Mac OS X?

If you create data files under Mac OS X in order to load them intothe Classic version of RasMol, you may need to set the 'creator'and 'file type' of the files to make then visible to Classic.

Apple provides a utility, SetFile, in the Developer Tools that will do the job.First you need to install the Developer Tools from CD or from the Appleweb site developer.apple.com/tools/download/. You should then be able to find SetFile at /Developer/Tools/SetFile. Usinga terminal window, change your directory to the one containing the file youcannot see and execute

/Developer/Tools/SetFile -c 'RSML' filename
/Developer/Tools/SetFile -t 'TEXT' filename

What is the relationship among the various RasMol web sites?

There is no connection between the molecular graphics program RasMol andthe rasmol.com web site. The www.RasMol.org, www.OpenRasMol.org and www.OpenRasMol.com sites are all the same site, the home page for the molecular graphic program RasMol.Eric Martz's site www.umass.edu/microbio/rasmol/is focused on Protein Explorer and Chime. Even though it is badly outof date with respect to RasMol, it contains a great deal of usefulinformation, and maintains a discussion list for those interested inRasMol.
