Hi, I am wondering about the alignment of sequence and PDB model in mr_rosetta - the program seems to complain if the sequences dont exactyl match - so is this really the case? (I have an initial model from autobuild with some fragments that do not have fully correct sequence - hence it doenst exactly match with the original sequence of the protein). Does it have to? Or should there be a way around it? also the command file examples online e.g. : phenix.mr_rosetta \ seq_file=seq.dat \ data=coords1.mtz \ search_models=coords1.pdb \ already_placed=True \ rescore_mr.relax=False \ rosetta_models=20 \ ncs_copies=2 \ space_group=p212121 \ use_all_plausible_sg=False \ nproc=200 \ group_run_command=qsub when using the command file all the commands are not recognized for some reason (running on a mac with bash shell) e.g. rescore_mr.relax=False, same with fragment files… not quite sure what the problems is there, probably something trivial. -if i just enter them on the command line it works. Thanks, Tommi
