holle,sir! nice to send a letter to you! (1) about FindHBond .I can find out some HBond between ligand and receptor,by chimera. I also use Accelrys Discovery Studio to find out some HBond . but Accelrys Discovery Studio find out HBond to be more than chimera. why?which one result is ture? (2)what is meaning about Clashes/Contacts?what is useful for Finding Clashes/Contacts (3)how can i find out interaction between ligand and receptor and classify displaying. (4)can i use this software to publicate my paper ,directly? best wishes for you !
(1) FindHBond vs. other programs. Different programs use different methods and cutoffs, and there is no reason to expect exactly the same results. The world of science does not agree on one exact definition of H-bond. Each program should explain its own method, as we have in the FindHBond documentation. Click "Help" on the FindHBond dialog or go here: <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/findhbond/findhbond...
Also, this same question was discussed 2 days ago on the chimera-users list, see: <http://www.cgl.ucsf.edu/pipermail/chimera-users/2010-January/004746.html
(2) What are clashes and contacts? This is explained in the Find Clashes/Contacts documentation. Click "Help" on the Find Clashes/Contacts dialog or go here: <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/findclash/findclash...
(3) use FindHBond and Find Clashes/Contacts. The "Structure Analysis and Comparison" tutorial is one example of using these tools: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/tutorials/ squalene.html> (4) yes, you can use images and calculation results from Chimera in your paper, but please remember to credit Chimera as described here: <http://www.cgl.ucsf.edu/chimera/docs/credits.html> Elaine ----- Elaine C.
