Actually, I try to do optimization on set of selected atoms with random
deviation 100 . Then later I realized that I cant keep random deviation
more than 0.5 for following these residue (HIS,TRY,TYR,PHE) and I have PHE
and HIS in my selected set.
So , I decided to keep the atoms of HIS,PHE as rigid by following these
set for optimization
r = rigid_body(selection(s).only_residue_types('HIS,TYR,TRP,PHE'))# By
this I select atoms of HIS,PHE from selected set to keep rigid
But, This doesn't work So could you tell me how to select atoms of
(HIS,TYR,TRP,PHE) residues from selection to make rigid ?
Thanking you in advance
