Normally, these days at least, a model that is result of TLS refinement
contains total B factor in ANISOU records and its TLS component in TLS
records (REMARK3), with Btotal = Btls+Bresidual.

If TLS matrices are available, it's trivial to calculate Btls from TLS
matrices in REMARK3 and subtract it from Btotal (ANISOU), which will give
you Bresidual.

Some of older PDB files are likely to have Bresidual in ATOM records and
TLS component in REMARK3 as TLS matrices. In this case, to get total
Btotal, you need to compute Btls from TLS and add to Bresidual.

I guess TLSANAL is the CCP4 tool to do this, and phenix.tls will do
conversion both ways as well.
