Plot 5. Side-chain parameters
Description
The five graphs on the side-chain parameters plot show how the structure (represented by the solid square) compares with well-refined structures at a similar resolution. The dark band in each graph represents the results from the well-refined structures; the central line is a least-squares fit to the mean trend as a function of resolution, while the width of the band on either side of it corresponds to a variation of one standard deviation about the mean. In all cases the trend is dependent on the resolution.Note. This plot is intended as a rough guide only and too much reliance should not be placed on getting results that are "better than structures at the same resolution".
The 5 properties plotted are:
- a. Standard deviation of the chi-1 gauche minus torsion angles.
- b. Standard deviation of the chi-1 trans torsion angles.
- c. Standard deviation of the chi-1 gauche plus torsion angles.
- d. Pooled standard deviation of all chi-1 torsion angles.
- e. Standard deviation of the chi-2 trans torsion angles.
Options
The main options for the plot are:-
- 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.
