DESCRIPTION
gmx xpm2ps makes a beautiful color plot of an XPixelMap file. Labels
and axis can be displayed, when they are supplied in the correct matrix
format. Matrix data may be generated by programs such as gmx do_dssp,
gmx rms or gmx mdmat.
Parameters are set in the .m2p file optionally supplied with -di. Rea‐
sonable defaults are provided. Settings for the y-axis default to those
for the x-axis. Font names have a defaulting hierarchy: titlefont -
legendfont; titlefont - (xfont - yfont - ytickfont) - xtickfont, e.g.
setting titlefont sets all fonts, setting xfont sets yfont, ytickfont
and xtickfont.
When no .m2p file is supplied, many settings are taken from command
line options. The most important option is -size, which sets the size
of the whole matrix in postscript units. This option can be overridden
with the -bx and -by options (and the corresponding parameters in the
.m2p file), which set the size of a single matrix element.
With -f2 a second matrix file can be supplied. Both matrix files will
be read simultaneously and the upper left half of the first one (-f) is
plotted together with the lower right half of the second one (-f2). The
diagonal will contain values from the matrix file selected with -diag.
Plotting of the diagonal values can be suppressed altogether by setting
-diag to none. In this case, a new color map will be generated with a
red gradient for negative numbers and a blue for positive. If the color
coding and legend labels of both matrices are identical, only one leg‐
end will be displayed, else two separate legends are displayed. With
-combine, an alternative operation can be selected to combine the
matrices. The output range is automatically set to the actual range of
the combined matrix. This can be overridden with -cmin and -cmax.
-title can be set to none to suppress the title, or to ylabel to show
the title in the Y-label position (alongside the y-axis).
With the -rainbow option, dull grayscale matrices can be turned into
attractive color pictures.
Merged or rainbowed matrices can be written to an XPixelMap file with
the -xpm option.
