Hi all,

I'm trying to refine a DAMAVER structure, as suggested by a Svergun's review, by using DAMMIN. When I ran DAMMIN with simmetry, I obtained this error:

DAMSYM --W-: Atom# 1 does not have simmetry mate

It would be helpful if you provide additional information and files to reproduce your problem.

1. which command/files did you use for refinement?
2. attach your input file
3. which OS and ATSAS distribution are you using.

Hi all,

I have a similar question. I am currently working on a protein that forms an octamer in solution (we have native MS, SEC-MALLS, DLS, analytical SEC, and SAXS to support this). I am no working on getting an ab initio shape.

I ran DAMMIF multiple times to generate about 20 ab initio models in various symmetries (P1, P2, P4, P8, P22, P42). I then wanted to get a final ab initio model via DAMMIN starting from the damstart model. This works for all, except for P8 and P42. When I try to start a DAMMIN run with those symmetries, I get the error message

Atom #x does not have symmetry mate
Assumed symmetry is P1!

I am running the latest ATSAS on a Mac OSX 10.13.6.

Any help or suggestions would be highly appreciated.

Kind regards,

hey there let me help you but you have to tell me what command you use which OS ATSAS distributiob you are using
