Ed, I would highly recommend Phaser to do what you want. Phaser can be configured to search all possible related space groups, or the ones you designate. Open-EPMR can also do automated related space-group searching as well.

Berry Sent: Monday, May 07, 2007 2:32 PM To: CCP4BB@JISCMAIL.AC.UK Subject: [ccp4bb] Alternate space groups for MR in Beast Dear All, I'm doing molecular replacement with beast, using the ccp4i gui. Space group is P41 or P43 based on syst. absences. Input mtz file is reduced in P41, but I want to try the translation search with both. So, Does beast automatically try both? Is there a parameter I can enter to set p43 on second run? Do I need to change space group of input file to test p43? Thanks, Ed
