Well P4 isnt a subgroup of P43212 - you would need P43
MR programs will often let you test several spacegroups. See Phaser MR or MOLREP - I would try that and choose the best

Dear experts, Sorry for a simple question but confusing me so much! Does it make bad effects on determining the number of identical molecules in ASU by choosing low symmetry space group. For example,If I choose lowest symmetry(p4) instead of higher one(p43212). Does it cause any trouble in determining structure while we try to find the solution by molrep. If molrep compare the patterson of observe and model in P1 space group, it doesn't matter in choosing a lower s.g.? Any suggestion will be appreciated. Thanks in advance. Ting wei
