[PyMOL] individual surfaces?
Dear PyMol users, I'm currently trying to display individual surfaces around different selections of a molecule to show how they contact each other. However, either I get only the last surface displayed or a joined surface using the command examples below: this one gives only the surface of residue 440 show surface, ( resid 431 ) flag ignore, ( not resid 431 ) show surface, ( resid 440 ) flag ignore, ( not resid 440 ) rebuild whereas this one gives the joint surface of residues 431 and 440 show surface, ( resid 431 or resid 440 ) flag ignore, ( not ( resid 431 or resid 440 ) ) rebuild How can I display the individual surfaces separately? Alternatively, is there a command to display atoms in a CPK representation?

RE: [PyMOL] individual surfaces?
Dirk, The trick for displaying contact surfaces in PyMOL is to create separate objects for each surface: create res431, resi 431 create res440, resi 440 show surface, res431 or res440 For CPK, you don't need to do this show spheres, resi 431+440 Cheers, Warren -- mailto:war...@delanoscientific.com Warren L.

RE: [PyMOL] incorporation of unusual amino acids
Uwe, We plan a research project where we want to stepwise incorporate D-amino acids into a peptide. To determine the exchanges it would be very useful if PyMol could assist. If I might dream I would like to have D-amino acids (and maybe other un- usual amino acids) available in the mutation-tool; You can flip residue 5 from L to D with the following two commands edit 5/ca invert 5/n, 5/c some simple energy minimization / bond relaxation; storing the resulting molecule in PDB- format. Sculpting can relax VDW/bond/angle strain, but it is not energy minimization by any means. Can I hope ? Is this something others find useful as well ? We'd all like to see a real forcefield in PyMOL, but no one has written the code yet. Cheers, Warren

To my surprise (naively perhaps) the standard RH-derived RPMs on the pymol site lead to chains of missing dependencies that I don't reach the bottom of. Eventually I got pymol working kind-of with pymol-0.82-2mdk.i586.rpm preceded by python-numeric-22.0-2mdk.i586.rpm I dealt with some Tkinter error messages by installing the appropriate rpm but now I have Traceback (most recent call last): File /usr/lib/python2.2/site-packages/pymol/modules/pymol/__init__.py, lin e 74, in exec_str exec s in globals(),globals() File string, line 1, in ?

The dependency chains when trying to install RH rpms were quite tricky and included some complaints about libraries that I could even see in /lib ! That completely flummoxed me.

[PyMOL] Re: PyMOL-users digest, Vol 1 #408 - 11 msgs
Hi List! I'm glad to see others enjoying MDK 9.1. But pymol rpm for RH is a friend of MDK, I suggest you use pymol-0_90-bin-linux-libc6-i386.tgz It works terrifically for me. Dear Warren, realy great job! If possible, a proper pymol rpm for MDK 9.1 would be very welcome, since I believe there's many MDK users of pymol like me and Dan.
