Autobuild uses phenix.refine: it iterates between model building and
refinement with phenix.refine.
Fore more details see this recent paper that describes it in details:

It seems to be a bug in PHENIX. Dale Tronrud reported a similar problem
(look mails with subject "Using the Same Test Set in AutoBuild and
Phenix.Refine"). If phenix.refine stops with "MD5" error message, a
temporary fix is: remove the corresponding line from your PDB file and
use your original reflection file in refinement. Let me know if you have
We are looking into this problem and hopefully it will be fixed once Tom
