Good morning Paolo, Yes, there is "sequential fitting" using the "fitmap" command. See here for explanations including command options and link to a short video: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/fitmap.html> <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/fitmap.html#sequence> There is also symmetric fitting of multiple copies of the same structure: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/fitmap.html#symmetric> I'd probably try the above first, but yet another related feature is MultiFit, which uses a web service (in menu under Tools… Volume Data): <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/multifit/multifit....> I hope this helps, Elaine ---------- Elaine C.

Good morning, I am EM user and I was wondering wether is possible in Chimera to fit multiple pdb in the same volume (e.g. Fitting two monomers into a dimer map without overlaps and clashes). I am using Situs and the collage command, but I was wondering if there was an easy way of doing it in Chimera. Thank you very much, Paolo
