The residual B factors are only one contribution to the mean square displacements, so don't read too much into the numbers. In particular, there is an ambiguity between the trace of T and the mean residual B factor - you can take a chunk out of Tr(T) and give it to all the atoms in the TLS group. T

[ccp4bb] TLS Refinement on ~3 angstrom resolution structures

2008-10-20 Thread Jim Fairman
Hello everyone, I have two structures of a protein bound to two different small molecules I am trying to refine with REFMAC5 from CCP4 v6.0.0. One has a resolution of 3.2 and the other has a resolution of 2.9. If I use TLS refinement parameters on these structures I can get the Rwork/Rfree down
