real space refine generates non-compliant PDB files
Not sure whether anyone would care now that we got our marching orders to abandon PDB format and move to mmCIF, but the output of phenix.real_space_refine includes a number of lines that are not legit PDB records, i.e. this section ... REMARK 3 GEOMETRY RESTRAINTS LIBRARY: CDL v1.2 DEVIATIONS FROM IDEAL VALUES. BOND : 0.004 0.049 74053 ANGLE : 0.747 12.299 100513 CHIRALITY : 0.052 0.232 11312 PLANARITY : 0.006 0.069 13125 DIHEDRAL : 11.589 179.958 44947 MIN NONBONDED DISTANCE : 2.276 MOLPROBITY STATISTICS.

This does result in errors when this output PDB file is used as input to other software that is more stringent with format compliance. Cheers, Ed.
This is fixed in recent versions (nightly builds): http://phenix-online.org/download/nightly_builds.cgi Pavel On 2/22/19 06:11, Edwin Pozharski wrote:
