[phenixbb] Short contact with symmetry mate

Dear Phenix BB, I am refining a helical bundle structure where I have been obtaining an invariant short contact (close to 2A) at a Glu residue with Lys of symmetry related molecule of one helix of the bundle. I had been using Rigid body, TLS, occupancy and Indv ADP for the refinement (which gave the best Rfree values). If I include coordinate refinement the short contact seems to be gone rather with higher Rfree values. I ll appreciate some suggestions regarding this. Thank you in advance.
