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