Hi, I am struggling to fit a model of a single protomer into a viral cryo-EM map. I usually succeed after a very long process of manually positioning the model approximately and then running 'fit into map' that arranges it in the best way. I filtered the map to low resolution and used the option to generate a density map of the pdb file which makes it easier but it is still complicated. However, I believe that there is a routine to globally fit that does not require the very cumbersome first manual fitting. Can anybody please give me a hint? Thanks a lot, Dieter ------------------------------------------------------------------------ Dieter Blaas, Max Perutz Laboratories Medical University of Vienna, Inst. Med.
