Hi Tim

use "wxu_scale" keyword for this. Making it less than the default value
will strengthen the ADP restraints and hence make ADP of adjacent atoms
more similar.

This is mentioned in the Manual although I admit is not too easy to
find. Look for "wxu_scale" in
http://www.phenix-online.org/documentation/refinement.htm
and you will find this among several hits.

Are you using TLS? How old is the version of PHENIX that you are using?

Cheers,
Pavel.
