you can fit your model chin A over chain B

First save chain A only to a new model either in COOT or outside by editing

so now you have two Models - one A B C etc , and one only A

Calulat SSM. overlap or some such instruction of A over B and change CHAIN ID to X say

Now repeat with SSM overlap A to C.. etc

At end you can mere A with all copies..

But also maybe better to sort out the true symmetry first.

Do you have a suggested Space group or is it really P1?

Dear Phenixbb and CCP4bb members,

I'm currently refining a structure and facing some problems. It's originally a tetramer in solution, but I could only solve it in P1 group, with 8 molecules in the asymmetric unit (two tetramers). One of my chains is complete, but the others present some significant gaps. I believe I can use one chain and apply symmetry operations in order to produce a tetramer, I've heard it is possible using Coot, but I've never done that. Any suggestions?

Best regards,

Lorenzo
