I'm trying to decorate some kegg pathway maps with expression data using the [KEGG Mapper from the kegg website][1].  
In the first text field I enter the kegg pathway of interest (zma00940) and then I upload a text file with my test data (see below).  I click 'exec' but I get an error: 0 does not exist. I guess there is some problem with the format of my data dont see what it could be.  Any help would be appreciated.

Apparently the KEGG color mapper requires a header row:

    #zma	count
    zma:100381820	20
    zma:100273579	5
    zma:103627433	1

When I add that to the file, it seems to work.
