Conversion of Chimera session .py file to Pymol .pse file
by Joanna Smietanska 01 Jun '20

01 Jun '20

Dear UMSF Chimera Users, I would like to ask how to convert Chimera session .py file into .pse Pymol format? I have a few saved Chimera sessions, my approach was to save protein coordinates in .pdb format and subsequently read them in Pymol 2.0 to save as Pymol session, but during this procedure all informations about specific colouring of chains and other settings are lost. May I ask about possibilities for direct import Chimera .py files into Pymol without losing saved settings? I would be very grateful for any help and advice. Best regards, Joanna Smietanska

Molecular dynamics
by Сергей Владимиров 01 Jun '20

01 Jun '20

Good day! My name is Sergei Vladimirov, I'm a student at Moscow State University. As far as I know, when running a molecular dynamics of ligand-protein interaction one must use different force fields to the ligand and the protein. There is a mm14ff to calculate interactions within a protein but there are only two different force fields to calculate interactions within a ligand. I've been led into believing that the best ff for small organic ligands is GAFF. So my question is, is there any way to implement the GAFF force field into the production of molecular dynamics? Is there anything I'm missing? I will be awaiting your reply. Best regards, Sergei Vladimirov.

Molecular docking
by Schaf, Judith (2017) 27 May '20

27 May '20

Hi everybody, I have a quick question: when I analyse the results of a molecular docking assay (performed with SwissDock) on Chimera I sometimes see a green line between the protein and the ligand. Does someone know what this line represents? [cid:fc8bd8ab-4117-464a-b2fb-0f512e867f88] Thank you, Judith
