Thanks for the prompt responses, Warren and Joe! Works like a charm! Now, I just wish that my Kensington Expert Mouse could function as a true three button mouse...is there a keystroke that mimics the third mouse button? Thanks again, james

Hi James, Sounds like you want a homology model type set up, ie generate coordinates based on a template. Modeller can do this and an easier way is via the swissmodel http://swissmodel.expasy.org//SWISS-MODEL.html If however you want a relatively random structure then pymol _can_ do this.

2005-08-10 Thread James R. Graham
Hello, This may be slightly off-topic, but I was wondering whether PyMol would allow one to enter a peptide sequence (generally short in length) to create a template structure that can then be used for structural refinements (minimizations, etc.) elsewhere. If PyMol cannot do this, is any

RE: [PyMOL] multi distance object to single distance objects

2005-08-10 Thread Warren DeLano
Dan, Sorry, that is not currently possible. In order to get individual distances, you need to create them one by one using a nested loop. Something like: for at1 in cmd.index("resi 10"): \ for at2 in cmd.index("resi 11"): \ cmd.dist(None, "%s`%d"%at1, "%s`%d"%at2) Cheers, Warren -- W

Hi Daniel, This problem has been tackled several times, maybe have a look at the following URLs, it might help you getting started: http://www.rubor.de/bioinf/tips_python.html#msdist http://sourceforge.net/mailarchive/message.php?msg_id=2914266 And also don’t forget the ‘search’ feature o
