matplot

Description

distmat produces several output files containing matrix data. matplot can be used to visualize these data as a 2D map plot.

Command summary

gmx_clusterByFeatures matplot [-h] [-i distmat.dat] [-o output.png]
                              [-xs 1] [-ys 1] [-xl Residue]

                              [-dpi 300]

Options

-i distmat.dat, --input distmat.dat

Input file containing matrix-data. This file is obtained as a output from distmat.

-o output.png, --output output.png

Name of the output matrix-plot file. The extension will be used to determine the output format.

Following output formats (system dependent) might be available:

  • ps : Postscript

  • eps : Encapsulated Postscript

  • pdf : Portable Document Format

  • pgf : PGF code for LaTeX

  • png : Portable Network Graphics

  • raw : Raw RGBA bitmap

  • rgba : Raw RGBA bitmap

  • svg : Scalable Vector Graphics

  • svgz : Scalable Vector Graphics

  • jpg : Joint Photographic Experts Group

  • jpeg : Joint Photographic Experts Group

  • tif : Tagged Image File Format

  • tiff : Tagged Image File Format

Note

To list the output formats, use gmx_clusterByFeatures matplot -h.

-xs 1, --x-start 1

First residue number along X-axis. Input file does not contain information about residue number. Therefore, this option can be used to set the number of residues along X-axis.

-ys 1, --y-start 1

First residue number along Y-axis. Input file does not contain information about residue number. Therefore, this option can be used to set the number of residues along Y-axis.

-xl Residue, --x-label Residue

X-axis label

-yl Residue, --y-label Residue

Y-axis label

-cbl (nm), --colorbar-label (nm)

Label for color bar

-a auto, --image-aspect auto

Controls the aspect ratio of the axes. The aspect is of particular relevance for images since it may distort the image, i.e. pixel will not be square.

Following two options are available:

  • -a equal : Ensures an aspect ratio of 1. Pixels will be square.

  • -a autoThe axes is kept fixed and the aspect is adjusted so

    that the data fit in the axes. In general, this will result in non-square pixels.

-cmap binary, --colormap binary

Name of colormap by which matrix image will be colored. To preview the available colormaps, visit colormaps list.

Following colormaps might be available:
