.. class:: warningmark

This tool requires that matrix2png be installed and available in Galaxy's PATH.

.. class:: warningmark

This tool requires tabular data with column AND row headers. For more information about the required format and usage instructions, see the matrix2png_ website.

.. _matrix2png: http://bioinformatics.ubc.ca/matrix2png/dataformat.html

.. class:: warningmark

It is recommended to specify the colorspace range since outliers will often skew it otherwise.
