Dear all, I tried to rebuild my structure from a refined model (by refmac) by phenix.autobuild. I am not sure if it runs properly since this is my first time to run this module....it took like almost a day to just finish the run_1 (there should be five runs by default?), which means it will take me another 4 days to finish the whole thing. My protein has around 350 residues and in the refined model, I have omitted some loops (about 80 residues) because I cannot see the electron density of those regions. I have put the seq.dat file with the full sequence (~350 residues) and the commands "place_water=Yes" and "s_annealing=True". The resolution is 2.4 A. Should it be taken so long to run? Thanks in advance!
