Hi Daniel,
I'm sorry for misunderstanding -
It's true that Apply only puts one copy in the structure, but if you
don't Apply and simply keep the Rotamer list dialog and choose all of
its lines, that displays all of the rotamers at the same time. Maybe
that would allow you to do what you want. The Rotamer list dialog
allows calculating clashes and H-bonds, plus selecting the rotamer
atoms so you can control their appearance with the Actions menu.
The issue is that the structure can't have multiple indistinguishable
atoms (with the same name and residue number). We have talked about
allowing multiple rotamers to be applied to the structure by giving
them different "alternate location" ID codes, but that has not been
implemented yet. Also, some residues may have more rotamers than the
number of possible alternate location ID codes. Nevertheless we will
make sure it is on one of our requested features lists.
So currently you can't save PDB with multiple rotamers, but you can
save/restore the session in the state where all of the rotamers are
displayed.
I hope this helps,
Elaine
