I am trying to run phenix.automr on what I believe is perhaps a perfectly twinned data set, at 3A resolution. It is in space group 146 and according to the matthews has 3 molecules in the asu. This is a mutant of an orriginally published structure in which only one residue has been mutated (but crystallizes in a different space group). When I give the autoMR the following input: phenix.automr coords="MR.1.pdb" data=dtscale.ref resolution=0 component_type=protein identity="95" mass=13900 build=False copies=3 seq.dat I get an LLG of 37 and the run goes quite quickly. The speed of the run itself leads me to believe that I have a correct solution regardless of the slightly low LLG, but when I open the .pdb output file there is only one molecule in the asu. Am I doing something incorrectly? Why is there only one molecule instead of 3 in the asu, and how can I go about getting the other two to appear? I did let the program go ahead run autobuild, this resulted in a structure with an r_work:.5448 and r_free:.6005. I am relatively new to crystallography, but these values seem rather high to be a good starting point for refinement. I would appreciate any advice that might help me move on with my structure. Attached is the log file from phenix.xtriage in case it may be of any help. Thank you, in advance, for all of your help and advice. Best Regards, George F. Feldman
