[phenixbb] NCS restraints with TLS

I am using NCS restraints with TLS. It seems that the NCS B-factor restraints are applied to the overall B-factor, rather than just the non-TLS part. Is this correct? In my structure, the disorder varies quite a bit among equivalent molecules, and I don't get good results unless the b_factor_weight is about 1e-3 or less. I am experimenting with NCS restraints in CNS, where each pair of coordinates allows an LSQ fit of B-factor scale and offset to be excluded from the B restraints. It would probably work even better with TLS, which CNS does not have. I don't know if anyone has tried this, but I think that overall molecular B-factor differences are fairly common. Joe Krahn
