I believe this is because of the overall B-factor for the entire
crystal ("Ucryst") being refined, which will happen no matter what.
Because phenix.refine reports the total atomic B-factors including all
contributions, this change will propagate to the atoms you've
excluded, even if their individual B-factors aren't being refined.
(Although it is also unclear why you wouldn't want to refine those
B-factors too - this is almost always recommended.) I guess we need
to add this to the phenix.refine FAQ list.
PS. please post with a new subject instead of replying to a previous
post, it makes a big difference for some email clients and our mailing
