For the record/archive I'd like to conclude this thread.
It recognizes the spacegroup as P 1 21/c 1.
Is seems that Coot indeed does display symmetry correctly for this spacegroup, but not in the way that other programs (e.g. Mercury or Swiss PDB Viewer) do.
coot> (show-spacegroup 0) "P 1 21/c 1" If I then ask coot to show-symmetry I get the following coot> (show-symmetry 0) Backtrace: In current input: 8: 0* (show-symmetry 0) <unnamed port>:8:1: In expression (show-symmetry 0): <unnamed port>:8:1: Unbound variable: show-symmetry ABORT: (unbound-variable)
You followed the instructions in the manual. I am sorry to say that there is a error there, it should have (and now does) read:
(get-symmetry imol) Thanks, Paul.
