Hi Haim, this should not happen, so yes, it is a huge deal. Please send me (to my email address, not the mailing list) the PDB files before and after refinement and I will have a look. Pavel On 1/23/13 6:25 AM, Haim Rozenberg wrote:

Hello, It seems that after "refine", the summation of occupancies is not always equal to 1.00 when more than two alternative conformations are defined in the pdb. In recently refined structures we were surprise to find 1.01 instead of 1.00 (Big deal ??? Yes, for the deposition/validation!). We didn't find any warning nor error messages in the corresponding log files.

(phenix.refine: 1.8.1_1168) or newer, on Mac as well as Linux machines.

Best regards, Haim
