If not clear, the template here is the fasta file. I wonder where Sali's modeller allows filling residues in a multimer by also taking into account the inetraction between the different subunits. Not seen any example. francesco pietra ---------- Forwarded message ---------- From: Francesco Pietra <chiendarret@gmail.com> Date: Sun, Jun 23, 2013 at 7:17 AM Subject: modeling multimers To: chimera <chimera-users@cgl.ucsf.edu> Hello: Modeling a trimer (all three chains present, though missing residues and atoms) with chimera and modeller installed locally. The default is modeling each chain, one at a time. The chains are identical in sequence but the X-ray structure shows different localized conformations. Question: is modeller modeling by taking the other two chains into account? If already answered, beg pardon. thanks francesco pietra
