I must also credit Robbie with the easiest (most elegant?) solution to
my question.
You run 0 cycles of refmac with the mixed B factor model.
Thanks all for your inputs.

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
Actually I think it is pretty dangerous to trust the TLS stuff in the PDB
header - there is a muddle between B_residual and B_merged and no adequate
description in the header.
Unless you are planning on doing many many repeats I would re-refine before
checking the map...

It would be nice to be able to run zero cycles of refmac to get a map
etc direct from a PDB file.
However due the PDB requiring the TLS component of B factor to be
included this does not work.
Is there software to remove the TLS component so a zero cycle of refmac
can be run.
