Macintosh

DISCLAIMER. We are not regular users of Macs. The instructions below have been tried on a Power Mac G3 PPC running OS 8.0 and work. They may need modification for other Macs.

Installing the Mac RasMol

The first difference on the Mac is that rasmol2.6b2 which is the version linked to on the installing page link has a bug not present in the other operating systems that means that some scripts hang - including the test scripts on the previous page.

Thus we recommend you get rasmol 2.7 from http://www.openrasmol.org. This is distributed as gzipped binaries which can be installed as described below.

  1. Download the binary either via Netscape or Fetch. Also download rasmol.hlp at the same time into the same directory.
  2. Check what the extension is; if it is .bin.gz run gzip on it.
  3. Once you just have a .bin file open it with Stuffit Expander which can be downloaded from http://www.stuffit.com/expander/
  4. You now should have a RasMol icon in the directory. You can click on it to start the program.

Configuring Netscape 4.7 on Macs

For the second of the two MIME types described below, the RasMol program needs to be called with the '-script' command-line parameter. Unfortunately, there is no way before OS X of issuing the equivalent of the 'rasmol -script' command. Instead the Mac version of RasMol depends on the 'type' information for the file. RasMol scripts are of type RSML (creator RSML), PDB files are of type TEXT (creator RSML).

You can alter these on downloaded files using freeware such as Resedit http://www.ResExcellence.com/support_files/resedit.shtml. However, you can tell Netscape 4.7 to assign these when downloading MIME types.

Repeat the following steps for both the MIME types you are defining:-

i. MIME type chemical/x-pdb

  1. From the Edit option on the menubar select: Preferences.
  2. Locate the Navigator entry in the Category column on the left. If its arrow points to the right, then click on the arrow to open up the subentries Languages, Applications and possibly Smart Browsing. (If the arrow is pointing downwards, then these should already be listed below the Navigator entry).
  3. Click on Applications.
  4. Click on New and fill in the form as follows:-
    • Description: PDB files
    • File extension: pdb, ent
    • MIME Type: chemical/x-pdb
  5. Mark Launch the Application: and press the Browse... button.
  6. Navigate to the directory containing RasMol.
  7. Select the RasMol program (probably called something like RASMAC_PPC_32BIT) and click Open.
  8. The extra step on Macs is to set the file type box to TEXT
  9. Click OK in the bottom right hand corner of the "New Type" window.

ii. MIME type application/x-rasmol

  1. From the Edit option on the menubar select: Preferences.
  2. Locate the Navigator entry in the Category column on the left. If its arrow points to the right, then click on the arrow to open up the subentries Languages, Applications and possibly Smart Browsing. (If the arrow is pointing downwards, then these should already be listed below the Navigator entry).
  3. Click on Applications.
  4. Click on New and fill in the form as follows:-
    • Description: RasMol scripts
    • File extension: rasmol
    • MIME Type: application/x-rasmol
  5. Mark Launch the Application: and press the Browse... button.
  6. Navigate to the directory containing RasMol.
  7. Select the RasMol program (probably called something like RASMAC_PPC_32BIT) and click Open.
  8. The extra step on Macs is to set the file type box to RSML.
  9. Click OK in the bottom right hand corner of the "New Type" window.

Configuring Internet Explorer on Macs

This browser is actually better on Macs than under Windows. Under 'Edit' 'Preferences' 'receiving files' 'file helpers', you get a very similar set of sections to fill in to the above. The difference is that the file extension is vital and you can only have one per entry. You can have the same MIME type assigned to several extensions in different entries.

Macintosh OS X

As this operating system is a 'linux for Macs' the Unix or Netscape 7 configuration instructions are likely to be closest for configuring for RasMol.

We have not tried this, so any comments from users to add to this section will be appreciated.

There are some links you could try in the first instance for more infomation:
