[phenixbb] Asymmetric unit content

Dear all, I have solved the structure in C121 space group, having five molecules in asymmetric unit, my supervisor have doubt about the fifth molecule becoz of poor density fit, if i delete the fifth molecule, there is a space for the molecule and crystal is not continuous, i calculated difference map from Phenix by deleting fifth molecule and got the Map showing presence of molecule. My supervisor want me to get SetMet data, but crystals are diffracting poor (7A). Is there any way to convince my guide. advance thanks for valuable suggestions. -- Sharan C/O Dr. J V Pratap Senior Research Fellow, CSIR-Central Drug Research Institute, Lucknow
