Dear Elke,
That seems to have done the trick. Can't thank you enough!!! I'm so happy.
For future readers:
ca6 alt loc A and residue 401 70% occ
pa3 #1 alt loc B and residue 402 30% occ
pa3 #2 alt loc C and residue 403 30% occ
I could have probably done pa3 #1 and #2 as the same residue 402 as I

Well - I made a copy of a ligand A 2001 and called it B 2001; gave each of
the "Ligands" occupancy 0.5, mangled the B molecule a bit and ran REFMAC .
It notes these atoms are too close but carries on refinement happily
enough..
But when I read the structure into COOT and try to refine the A

The sum of occ in these three is 1.3 and it looks like you put the occ in
the B-factor column.

Dear everyone that replied, thanks so much for the help thus far.
Just for info I’m using Coot for Windows version 0.9.6 EL and phenix.refine
version 1.20rc4-4416-000
RE Eleanor: It appears my version of coot/refmac do not support separate
ligands in the same space at <0.5 occupancy. As an
Dear Stuart,
you have to add
allow_duplicate_sequence_numbers()
to $HOME/.coot.py in OSX or the appropriate place on Windows. For
Windows, as there is no $HOME, Coot uses .coot.py or .coot-preferences/
directory for configuration - these can be found (added to) the
directory in which Coot
One may need to set a preference in Coot to allow such a situation to be
viewed. Paul helped me but I can't find the email.

I thought that REFMAC tolerated dual occupancies if the sum of the two
conformers was <= 1.0?

Will test..

Hi Stuart,
the answer, I think, is here:
