In order to project the chosen classifier onto KEGG pathways, you have to get to the KEGG “color pathways in gene maps” page ( here ).
Don’t forget to precise that you search against Saccharomyces cerevisiae ! (cf. besides)
Enter the file name containing the separator you want to project (the file must be something of the form separator.threshold.XX.colors.txt) and click on the “exec” button.
