Peter,
adptbx.u_as_b(-1) = -78.96.
When you read in a model with ANISOU records the equivalent isotropic B
is ignored but instead the anisotropic one is read in. After you did
your manipulations you write out a PDB file with isotropic ADP which
results in -78.96. I quickly looked at your code and it seems to me
that you don't take this into account. Please use or look for an example
in model.py facility to write out a PDB file: this is the common place
we use to write PDB file after phenix.refine. Please let me know if it
needs to be adjusted for your particular task or feel free to do it
yourself.
Pavel.
