Hello, I was wondering whether there is an infrastructure in one of the BioC packages to extract connections between members of the KEGG pathways. As far as I can tell KEGG package allows to get the identifiers of the members very easily, however I do not see a way of going one step further so to be able to produce a graph (where presence of each edge indicates known interaction or same compound ) Thank you. Any help /suggestion is greatly appreciated.

Hi Jane, here's what Imre Vastrik from Reactome said regarding your question: "We probably can't help with KEGG ;-). Reactome content is projected into pair-wise interaction space (see http://www.reactome.org/download/interactions.README.txt). The data (human only) is available at: http://www.reactome.org/download/current/homo_sapiens.interactions.txt .gz I imagine that another bit of useful information would be the association of sequence identifiers with pathways (not contained in the file above) so that one can go from a pathway to identifiers and for an indentifier to pathways." ---- There are a number of additional datasets in different file formats to download http://www.reactome.org/download/ Cheers Wolfgang ------------------------------------- Wolfgang Huber European Bioinformatics Institute European Molecular Biology Laboratory Cambridge CB10 1SD England Phone: +44 1223 494642 Fax: +44 1223 494486 Http: www.ebi.ac.uk/huber ------------------------------------- Jane Fridlyand wrote: > Hello, > > I was wondering whether there is an infrastructure in one of the BioC > packages to extract connections between members of the KEGG pathways.

There is some stuff done in the cMAP and pathRender packages, but this has not progressed that far, mostly due to a lack of resources cMAP is a meta-data package which has information from both KEGG and BioCarta (original data from the NCI) pathRender is in the development archive best wishes Robert Jane Fridlyand wrote: > Hello, > > I was wondering whether there is an infrastructure in one of the BioC > packages to extract connections between members of the KEGG pathways.

Another issue is availability of cMAP data: data for download is very different from that driving cMAP online querries. The downloadable data is only a small subset of online data, and there are quite some discrepencies between the two. The downloadable data is unchanged since early 2005.
