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.
