I would like to ask for advice concerning 'Fit rotatable H or D'
refinement stage in phenix.refine.
I am attempting to run unconstrained refinement on a certain
high-resolution protein dataset: just XYZ and ADPs refinement for every
single atom in the structure, with hydrogen atoms treated with
It turns out that when I set more then 3 macrocycles, the 'Fit
rotatable H or D' refinement stage is activated in every macrocycle
prior to 'XYZ individual' refinement stage.
I am using version 1.9, release 1692 for windows.
When I last worked with PHENIX, it was distribution 1342, and I am
positive I have not come across such refinement stage. It seems that
TARDY is involved at that stage.
As I specifically do not want to introduce any kind of torsion angle
dynamics in my current refinement, I would like to ask, what
command/option shall I use to deactivate this stage of H-atom fitting in
