Hi, thanks everyone for replying. However the question was a bit different ... - I already had my nice map, and I saved it in a pymol session. - I don't remember the *sigma level at which I generated it* - I wanted to know if I could figure this out without generating a new one and comparing by eye. Anyway I think that the less time consuming option is just to generate a new map. All the best, Almudena. 2015-07-21 11:46 GMT+02:00 <[log in to unmask]>: > This is interesting!
