Hi, fellow bioconductor members; In my memory, there is a vague rememberance that this is a package in Bioconductor called Pathway, I went to Bioconductor site , could not find a package named pathway in release 1.5, did I remember it wrong? Or the package is in an older release? If it is, which release it is? how do I access it? Thanks for all your help in advance Josephine

There is a KEGG package, and we also have KEGGSOAP that give you access to the KEGG data (for non-commercial use, if I recall correctly). You can supplement this with the graph package, RBGL and Rgraphviz to do most of the pathway stuff you want to. Another option is to make use of the CMAP data, which is potentially more interesting because it has the pathways already represented as a graph. But it is also more work as we have not managed to build any interfaces for this (they have some though); the url is http://cmap.nci.nih.gov/PW Robert On Dec 16, 2004, at 3:11 PM, Josephine Liang wrote: > Hi, fellow bioconductor members; > > In my memory, there is a vague rememberance that this is a package in > Bioconductor called Pathway, I went to Bioconductor site , could not > find a package named pathway in release 1.5, did I remember it wrong? > Or the package is in an older release?

Hi, Regarding Pathway analysis: In bioconductor when I load: library(KEGG) I can do this: kegg <- as.list(rae230aPATH2PROBE); and I can generate heatmap of pathway probes which are involved in my DEgenes so, I can see which genes are up and down in perticular pathway. how can I use interaction data extracted from human BioCarta pathways for my differentially expressed genes? if anyone has done please let me know...

I haven't tried anything other than loading the XML file, but that is pretty straightforward. Simply download the file: ftp://ftp1.nci.nih.gov/pub/CMAP/BioCarta.xml.gz Unzip it and change the first line to: Then, in R, open the XML library: library(XML) biocarta <- xmlTreeParse(file='BioCarta.xml',asText=F) Of course, BioCarta.xml has to be in the working directory or you must give the correct path. You can then use the XML package to do manipulations of the resulting data. Sean On Dec 17, 2004, at 9:29 AM, Saurin D.
