Dear community,
While refining a crystallographic model at 3.3 Å resolution, I noticed
an improvement in the geometry statistics after adding hydrogen atoms
in riding positions.
This is sad to hear. What geometry statistics in particular do you mean?
Anything to do with Coot?
(For the record, in Coot, for the non-bonded contacts, you'd be swapping
between the use of vdw_radius and vdwh_radius - that will cause some
differences, I imagine, but not a great deal - so if that is the case,
I'd be interested to know more).
Paul.
