> Hi chimera users, I was wondering if there is any way to build an average pdb from an Amber MD simulation of a system that doesn't contain any biopolymer. I know there is a script within the Amber suite, to generate an average pdb, but I'm doing the MD in several parts, and then reimaging them, so I wanted to check if the results of the Amber script, that makes an average on the coordinate file (.rst) without centering the system, is the same that I could have after applying the reimaging-centering script.
There is, sort of, but you have to modify your copy of Chimera -- though the modification isn't difficult. In the file <your Chimera>/share/Movie/average.py there are two calls to the "anaysisAtoms" function (on lines 22 and 47). If in both those calls you change "polymericOnly=True" to "polymericOnly=False" then you should be able to do the averaging you want.

P.S. On a mac, "<your Chimera>" will be "Chimera.app/Contents/Resources". Let me know if you need more info than that...
