PROCHECK sample plots

Plot 9. RMS distances from planarity

Description

These histograms show the RMS distances from planarity for the different planar groups in the structure. The dashed lines indicate different ideal values for aromatic rings (Phe, Tyr, Trp, His) and for planar end-groups (Arg, Asn, Asp, Gln, Glu). The default values are 0.03Å and 0.02Å, respectively, but these values can be altered by editing the procheck.prm file.

Histogram bars beyond the dashed lines are shown as highlighted.

Options

The main options for the plot are:-

• RMS distance from planarity for highlighting outliers for ring groups (default is 0.03Å).
• RMS distance from planarity for highlighting outliers for other groups (default is 0.02Å).
• The plot can be in colour or black-and-white.

These options can be altered by editing the parameter file, procheck.prm, as described here.
