[chimerax-users] mmcif assemblies for alphafold prediction

[Noriega, Heather]

Yes, so that is what I did. The "4 and 6" are the number of the assemblies
I wanted to recreate which is the asymmetrical unit and crystal version of
the unit. I did open up 1LP3 from the PDB bank super imposed to my alphfold
prediction with matchmaker and then used the sym command for assembly #4
and #6. However, only the 1LP3 create the sym. The alphafold stays as a
single superimposed monomer and I don't know why or how to fix it.

Thank you,
