Re: [PyMOL] Periodic boundary conditions?

2012-05-14 Thread Tsjerk Wassenaar
Hi Boris, PBC have not yet found their way to the main pymol code. What kind of stuff do you need? lattice.py is quite convenient for shifting. For (a)symmetry mates, you can use the scripts suggested by Thomas. If you need something else, pbc operations are not very hard to script. Cheers, Tsje

Re: [PyMOL] Aligning Pymol session files corresponding to different molecular dynamics snapshots

2012-05-14 Thread Thomas Holder
Hi Sajeewa, have you tried one of the alignment commands (align, super, cealign)? http://pymolwiki.org/index.php/Align You can't align "files", only "objects". So if your session files contain only one object each, this is trivial. If they contain multiple objects which need to be aligned in c

Re: [PyMOL] cylindrical helices

2012-05-14 Thread Dr. Mark Mayer
Hi Thomas, Thanks for input - the 'bug' was because the misbehaving PDB had ACs for residues in the helices that were not being drawn correctly. Stripping out the alternative conformations fixed problem, and dss forces cylinder to match dssp header, so I'm good. Mark >Hi Mark, > >cylindri

Hi Boris, if you want to visualize neighboring cells, have a look at one of these script from the PyMOLWiki: http://pymolwiki.org/index.php/Supercell http://pymolwiki.org/index.php/SuperSym Or for symmetry mates within a given radius: http://pymolwiki.org/index.php/Symexp Hope that helps. Chee

Re: [PyMOL] cylindrical helices

2012-05-14 Thread Thomas Holder
Hi Mark, cylindrical helices just connect start and end of continous helix annotations. Could it be that those "misplaced" helices just have a strong bend to one or both ends, pulling the cylinder from the major axis of the helix? Same with the fused helices, are you sure there is at least one

[PyMOL] cylindrical helices

2012-05-14 Thread nih\mayerm
I've run into a problem not encountered before: drawing a cartoon with cylindrical helices does not accurately follow secondary structure (a couple of helices are badly misplace and another 2 helices fused into 1) even though pdb has secondary structure defined by dssp in header. A cartoon with

2012-05-14 Thread Boris Kheyfets
Hello PyMOL users! I was wondering if there's a way to enable periodic boundary conditions in PyMOL? I found a script called lattice.py in the mail archive, but the message is 3 years old - so I thought may there have appeared a built-in solution? Search on pymolwiki reveals nothing. With great

I use PyMOL 1.4.1 which I have compiled myself. Now I'd like to switch to the latest version, so I checked out the latest svn, have enabled VMD plugins (and have also increased the fonts). I get the following error during compilation: contrib/uiuc/plugins/molfile_plugin/src/basissetplugin.c: In fu
