These auxillary compound ID mappers connect KEGG compound/glycan/drug accessions to compound names/synonyms and other commonly used compound-related IDs.
These auxillary gene ID mappers connect different gene ID or annotation types, especially they are used to map Entrez Gene ID to external gene, transcript or protein IDs or vise versa.
Molecular data like gene or metabolite data are frequently annotated by various types of IDs. This function maps and summarize molecular data onto standard gene or compound IDs. It would be straightforward to integrate, analyze or visualize the "standardized" data with pathways or functional categories.
node.color converts the mapped molecular (gene, protein or metabolite etc) data as pseudo colors on pathway nodes. col.key draws color key(s) for mapped molecular data on the pathway graph.
