Dear all, I have hit a wall when trying to get KEGG pathway maps colored by gene expression. On several of these, an entity on the map corresponds to several genes. I assume that the entity corresponds to one kegg orthology ID (at least that is what I observe in the pathways that I use). Now I face the following problem: KEGG API does not seem to have a consistent behavior when multiple genes with different colors are submitted to the color_pathway_by_objects. One way would be to use the get_elements_by_pathway SOAP call, since it returns a mapping between the graphical elements of a pathway and the genes in question. However, this does not seem to be implemented in KEGGSOAP. What do you do in such a case? Kind regards, j. --
