Hello all,

I am trying to use the "HeatMap" function in Mtalab, however it is not working. I keep getting an error message (??? Undefined command/function 'HeatMap'.). I have version 7 of matlab.
I also tried the file exchange for obtaining heatmaps, and I also get a error message in line 82.
Is the heatmap function working or not?
Thank you
ZA

Well, the message seems pretty clear to me.
Matlab cannot find HeatMap.
In other words, HeatMap.m does not exist on Matlab's path.
Either you are missing the file altogether, or you need to set your
path to point to its location (in File/Set path).

This object was introduced in Bioinformatics Toolbox 3.4 (release R2009b):

http://www.mathworks.com/access/helpdesk/help/toolbox/bioinfo/rn/br3_2_k-1.html#br8ra2v-1

If you do not have this version or later of this toolbox, you will not be
able to use this function.

However there is a submission called Customizable Heat Maps in the File Exchange which may do what you need.
