RE: [PyMOL] distance between aromatic residues

2005-05-24 Thread Grégori Gerebtzoff
Hi Sara, I don't think this is directly possible, since the centers of the aromatic rings are not declared per se. But I see another way to obtain the result you want, maybe this can be written as a small Python script (sorry I never wrote any Python scripts, so I can't translate my idea!!). The i

A more informative distance to measure between two aromatic (or planar) groups would be the plane-to-plane separation. I don't know how to code that, but if anyone out there has done, maybe it would make a handy addition to the set of tools. Pierre Rizkallah ***

[PyMOL] non-round helix bug

2005-05-24 Thread Björn Kauppi
Warren, et al, I discovered a funny bug in 0.98. If one turn off round helices and turn on cartoon highlight color: like; set cartoon_round_helices, off set cartoon_highlight_color,grey50 the highlight color and helix colors are mixed up!! Björn ***

[PyMOL] radius of gyration

2005-05-24 Thread Sara Nichols
Hi List, After a quick search of the list archives and the wiki, I couldn't find information about calculating the radius of gyration. Is this possible in pymol? And if it is, can you select specific residues and calculate the radius of gyration of your selection? Thanks in advance, Sara

This would be a nice option to have incorporated into pymol, and is a relatively short amount of code. In the meantime, I have a fortran program that will read a pdb file and calculate these values. Feel free to contact me off-list if you need it. Cheers, Steve -Original Message- From:
