[PyMOL] Installation of PyMol on Macs
I found the receipes on your homepage to install PyMol on Macs kind of convoluted, so here is what I figured after some working hours: Installation on Mac-OsX 10.2 1) Download fink from www.apple.com and install 2) add source /sw/bin/init.csh to /etc/csh.login to let the system know about fink 3) sudo fink configure (give as proxy something like http://www-cache.fh- giessen.de:3128) 4) get cvs-proxy..info and cvs-proxypatch from http:// fink.sourceforge.net/faq/usage-fink.php and put them into /sw/fink/dists/local/ main/finkinfo 5) sudo fink install cvs-proxy 6) cd to folder pymol-0.86; sudo fink update-all 7) open X11-Terminal 8) start pymol: /sw/bin/pymol Best Uwe Hobohm
[PyMOL] non-related question related: electrostatics
Hi All- I'll ask my related question first: does anyone know if/when electrostatic calculations might be incorporated into pymol? Or if you can import calcs from another (hopefully free) program? Unrelated question: does anyone know of a secondary structure prediction program that outputs pretty graphics to related 'helix' and 'sheet' structures? similar to how ESPript outputs ... but i do not have an input PDB file (yet) to use that program Thanks, Doug
RE: [PyMOL] q: discrete colors and adjacent cartoon segments
Bartholomeus, You have run into limitations in PyMOL's handling of single objects. The answer to both these questions is to split your molecule into multiple object and color/show independently. Use the create command to make copies, and then use alter to reassign secondary structure codes where needed. Warren -- mailto:war...@sunesis.com Warren L.

I'm puzzled with a coloring problem while coloring a protein molecule accordingly to its secondary structure by using 'discrete color' option: If there are a helix and/or strand adjacent together (e.g. helix from 1-10 and sheet from 11-20) the small pseudo-loop region between (arising from atoms between last Calpha of the helix and first Calpha of the strand) gets colored like the latter partner (maybe because of its color was defined at last). What I'd like to do is to color this small pseudo loop in a different color. I've tried to color the atoms between last Calpha and next Calpha (C,N) individually but there was no effect. It seems to me, that cartoon coloring only corresponds to Calpha positions. So, is there a way around to color cartoon regions between secondary structure elements as described before? 2. Is there a way to force PyMol to draw a cartoon which shows two different secondary strcuture elements (helix, strand) ending and beginning at the same residue? Maybe one can image a scenario where the N atom makes a strand-like conformation while the CO group of the same residue starts with a helix. In another program it is/was possible to assign helix and strand ending and beginning in the same residue but when I try to perfom with PyMol only the last partner is shown correctly while the first partner gets overrided in its last residue, e.g. cartoon strand 1-10 and helix 10-20 looks the same like strand 1-9 and helix 10-20. How one could circumvent this dilemma? Many thanks in advance!

RE: [PyMOL] stop an accidental or problematic ray trace
Anthony, I agree that we need one, but it doesn't currently exist. The same can be said for surface calculations, especially when you've loaded a 500 frame MD trajectory and accidentally show surface (doh!). My advice: save sessions often and make liberal use of PyMOL's logging capability. When you goof up, kill the process and then reopen the session or resume the log file after editing out the offending command(s). Cheers, Warren (Hmm...A save session button might be nice...) -- mailto:war...@sunesis.com Warren L. DeLano, Ph.D. Informatics Manager Sunesis Pharmaceuticals, Inc. 341 Oyster Point Blvd. S.
