Short description of Advanced Pathway Painter 2.23: This program visualizes pathways (KEGG, BioCarta, GenMAPP). The user can display any kind of quantitative data from gene and protein experiments directly within the pathways (colours represent the value). The linking between the pathway items and the experiment data is done over the gene or protein names and their accession numbers. Furthermore the user has a quick overview on the gene/protein with the collected direct links in the web interface.
