This page provides local copies of the RasMol program v2.6b2a. Although this is not the latest release, it has thus far been fine for use by our Biochemistry students.
The very latest release is 188.8.131.52. This is a collaborative effort and is still under development. Download the latest beta test version from http://openrasmol.org/
For instructions on how to use RasMol, take a look at the online RasMol Manual.
For more information about Rasmol and for links to other Rasmol resources, have a look at the Rasmol/Chime Home Page set up by Erik Martz at the University of Massachusetts.

RasMac2.6-PPC.sit.hqx - RasMac version 2.6 Beta-2a for Power Macintosh (PPC)
If the web browser does not unstuff the files automatically, save the file, then use StuffItExpander to decompress the file. The StuffItExpander utility is available from the Curtin Public Domain server under Macintosh:Utilities:Compression Utilities:StuffItExpander4.01(full). In this directory you will find the file 'StuffItExpander 4.01 Installer'. Double-click on the Installer file and follow the instructions for installation on your Macintosh hard drive. The StuffItExpander utility is also available on the web, try Aladdin Systems for the latest version.
Move the RasMac directory onto your hard drive. You should then configure your web browser to recognise RasMac as a helper application.
This is a compressed file which unzips into a RasWin directory with the 32-bit RasWin v2.6 Beta-2a application (rw32b2a.exe) along with two help files (rasmol.hlp and raswin.hlp) needed by the application. The directory also includes a manual for the original RasMol v2.5 plus an abbreviated reference card. Note that the online RasMol Manual has been updated for version 2.6.
Use a decompression utility like PKUnzip to unzip the PC file if your web browser doesn't do so automatically. PKUnzip is available from the Curtin Public Domain Server under PC:UTILS:ARCHIVE:PKZ204G.EXE. Create a new directory (PKUNZIP) and download PKZ204G.EXE into this directory. Run PKZ204G.EXE under DOS. It will create the PKUnzip executables plus all documentation for the program. PKUnzip can also be downloaded from the web. Here is one site.
The 32-bit version of RasWin will run under Windows95 or WindowsNT as is.
Instructions for installation are found at the Microsoft site.
Once you have downloaded RasWin and installed Win32s, create a new program item for RasWin. In Windows, select File, New (Program Item), Browse, and select C:\RASWIN\RW32B2A.EXE, OK. In the Description field, put RasWin followed by the version you are installing (for example RasWin32 2.6 Beta2). In the Working Directory field, put C:\RASWIN or wherever you plan to keep your scripts and PDB (atomic coordinate) data files. You should also configure your web browser to recognise RW32B2A.EXE as a helper application.
