I have been trying to find in the documentation if there is a way to do this
but I have the following problem: In a recent structure we are currently
refining we identified a spermine molecule sitting right on a
crystallographic two-fold axis. Spermine has internal two-fold symmetry and
it is part of extensive crystal contacts. I just wonder how to refine this
with Phenix. In Refmac it is easy, I put the occupancies to 0.5 and the
program ignores the clashes of the symmetry related molecule, but that
doesn't seem to be the way that Phenix works. Can anyone give me advise on
this?
Thanks
