Dear all, I have a dataset, there are 4 or 5 copies of two different hetero dimers (i.e. 4 different chains) in au, and I'd like to use the dimers as search models. I ran phenix.MRage with a phil file below, and it searched each chains separately, as expected. In this case, I want to search dimerA (containing chain1 and 2) and dimerB (chain3 and 4) as 2 search templates, but I couldn't find how to specify a dimer as a component. Using dimer.pdb and dimer.seq caused an error (sequence file can't contain multiple sequence). How do I write an input file? Regards, ------------------------- composition { count = 5 component { sequence = dimerA-chain1.seq stoichiometry = 1 template { pdb = dimerA-chain1.pdb } } component { sequence = dimerA-chain2.seq stoichiometry = 1 template { pdb = dimerA-chain2.pdb } } component { sequence = dimerB-chain3.seq stoichiometry = 1 template { pdb = dimerB-chain3.pdb } } component { sequence = dimerB-chain4.seq stoichiometry = 1 template { pdb = dimerB-chain4.pdb } } } ------------------------- ----- Takaaki Fukami (mailto:[email protected]) Discovery Research Dept.
