Dear All,
I am trying to make a custom covalent bond with an inhibitor compound and my protein. Plesae see the attached file for restraints file. But phenix is returning this error. Please help.

Sorry: No atom selected: 'chain S and resid 501 and name C7

I am using version1.6-289

Thanks.
Jobi

atom_selection_2 = chain A and resid 25 and name SG

distance_ideal = 2.35

sigma = 0.1

slack = None
