It is giving the error when formatting a new pdb file for writing out the refinement results. For some reason the b-factor refinement is unstable. Could you send me (directly, not the list) the inputs for debugging? I'll need the pdb file, the reflection file (usually mtz), the .eff file from the run that crashed, and any .cif files in case you have ligands.

 Dear Phenix Experts:
 My phenix.refine has developped the following error (see below). I tried
 to check my PDB format, there is not B-factor error. so what could be
 wrong that stoped my phenix.refine without PDB  and .def files in
 the output?
 Many thanks for your advice.
