[phenixbb] missing statistics for rama-z

[Hannah Bridges]

Hello,

I have a PDB for which, when I run either realspace refinement or 
validation, phenix does not show rama-z scores for helix or sheet (and 
the structure is not entirely loops..)

Rama-Z (Ramachandran plot Z-score):
   Interpretation: bad |Rama-Z| > 3; suspicious 2 < |Rama-Z| < 3; good 
|Rama-Z| < 2.
   Scores for whole/helix/sheet/loop are scaled independently;
   therefore, the values are not related in a simple manner.
     whole: -0.68 (0.08), residues: 8101
     helix:  None (None), residues: 0
     sheet:  None (None), residues: 0
     loop : -0.50 (0.06), residues: 8101

It seems peculiar to this one model, as other very similar ones are 
fine, but is this something that other people have seen before? I can 
supply the PBD off-list for investigation.

Best wishes

Hannah
