PROCHECK parameters
3. Chi1-Chi2 plots
There are 7 parameters defining the
Chi1-Chi2 plots, as follows:-
3. Chi1-Chi2 plots
------------------
-3.0 <- Cut-off value for labelling of residues
N <- Produce a COLOUR PostScript file (Y/N)?
WHITE <- Background colour
CREAM <- Lightest shaded regions on plots
GREEN <- Darkest shaded regions on plots
YELLOW <- Colour of markers in favourable regions
RED <- Colour of markers in unfavourable regions
Description of options:-
- Cut-off value for labelling of residues - The first option
defines the G-factor values below which residues on the Ramachandran
plot will be labelled. The G-factor gives a measure of how far from
the `normal' regions of the plot each residue lies. Low G-factors
indicate residues in unlikely conformations.
- Produce a COLOUR PostScript file - This option defines whether a
colour or black-and-white plot is required. Note that if the Colour
all plots option is set to Y, a colour PostScript file will be
produced irrespective of the setting here.
The colour definitions on the following lines use the `names' of each
colour as defined in the colour table at the bottom of the parameter file
(see Colours). If the name of a colour is
mis-spelt, or does not appear in the colour table, then white will
be taken instead. Each colour can be altered to suit your taste and
aesthetic judgement, as described in the Colours section.
- Background colour - This option defines the background colour of
the page on which the plots are drawn.
- Colours - The various additional colours on the lines that follow
define the colours for the lightest- and darkest-shaded
regions of the plot, and also the colours of the residue markers in the
favourable and unfavourable regions.
