Hello, I have same problem as in the following link which is the previous thread in this bb. If you solved the problem who posted, please let me know the solution how it can be tackled. http://www.phenix-online.org/pipermail/phenixbb/2009-April/013136.html I am trying to find 6 copies in ASU. The space group of diffraction set is P3121. I have obtained one copy with high TFZ scores (18.5) without clashes. However, while searching for second copy, Phaser gave so many clashes with no solution. As I read in above thread, it could be due to parallel pseudo-translation symmetry. Can somebody suggest me to overcome this type of problem? Regards, Rojan
