Thanks a lot for the detailed answer and the files - indeed there's a quite strange discrepancy in just the y coordinate. I'll look into this more closely. Incidentally, I just found a note in the cctbx documentation: http://cctbx.sourceforge.net/current/c_plus_plus/classcctbx_1_1uctbx_1_1unit__cell.html#_details So apparently the "PDB convention" corresponds to the 2nd IT matrix (and cctbx can be trusted about this). ... Now I have to figure out where this discrepancy comes from. Vincent ------------------------------------------------------------------------------ Xperia(TM) PLAY It's a major breakthrough.
