[phenixbb] X-ray/Neutron joint refinement

[Emily Golden]

Hi All,

I have a couple of questions about X-ray/neutron joint refinement in
phenix.

Is it possible to use the neutron data only for refining hydrogen atom
positions and the X-ray data for all other atoms?

I used the option to add hydrogen atoms to model and refine H/D at
exchangable sites and H elsewhere.

This worked for many of the exchangeable hydrogen atoms.  However, for some
side chains, especially Lysine, the program has placed a hydrogen and
deuterium atom (with refined occupancies) in the same position as the atom
it is supposed to be bonded to.

Does anybody know why this is happening and what I may be able to do about
it.  Or will I need to manually move each misplaced H/D in Coot?

Thank you for your help.

Emily
