Hi Bala, Since you can't control the resolution of the experimental density map, I'm guessing you mean what resolution value to use for the map simulated from the atoms that are being fit into the map (simulating a second map allows scoring the fit by map-map correlation). I believe you would want to use the same or similar value to the experimental map's resolution. In turn, that value should be available from the database where you got the map and/or the publication describing the map (or if not publicly available, the scientists who did the experiment). I hope this helps, Elaine ----- Elaine C.

Friends,
I am a newbie to fitting molecular structures on a volume map. I would appreciate if someone could suggest me some guidelines to choose an optimal resolution of the map before fitting.
Thanks, Bala
