I'm guessing the helices_strands.pdb file got corrupted somehow.
Does

phenix.pdb.hierarchy helices_strands.pdb

give clues?

Subject: [phenixbb] Problem with Autobuild

Dear All,
I am trying to run Phenix autobuild using the helices-strands.pdb obtained using find helices and strands program.
But the program is not running with the following error message.
The file helices_strands.pdb does not seem to be a PDB file

Thanks.
Jobi
