Hi, I have a quick question about your program. Normally (on a day to day basis) I use fairly basic features of chimera (coloring, etc) to produce pictures of crystal structure images (for presentations, papers, etc). Rarely do I have to use the more advanced features of chimera (Solvent accessible surface area, distance calculations, etc) so I don`t have a good idea of the limits of your program. Thus, I figured I would check to see if what I wanted to do is out of the scope of your program. I have a few crystal structures which I want to align (I now understand how to do this based on your online tutorial (thanks)), but what I really want to do is feed a third structure into the consensus structure (or if there is no consensus structure, just feed a known sequence into a known crystal structure to see if the sequence could form that structure. Is there anyway to do this in your program..
