Hi, I am trying to install the paeg1acdf and probe files from the Meta data site on to my windows platform. paeg1 P. aeruginosa Source,Win32 Source, Win32 The paeg1acdf was installed properly but the paeg1aprobe could not be installed. First of all the probe directory is called "paeruginosaprobe" and can be installed with that name. However, Bioconductor looks for the name "paeg1aprobe" when installing with gcrma, for instance. >>Error in getProbePackage(probepackagename) : >> Environment paeg1aprobe was not found in the Bioconductor repository. This message comes when the directory name is changed to 'paeg1aprobe' before install: >>Error in library(pkg, character.only = TRUE) : >> There is no package called 'paeg1aprobe' (I could try changing the name after install?) Can someone suggest something to help me get the probe file installed? Lana [[alternative HTML version deleted]]

You should be able to do this by sending your browser to the following URL: http://www.bioconductor.org/data/probes/Packages/ paeruginosaprobe_1.0.zip Then in the R Windows GUI there is a menu option to install a package from a local zip file. I'm not sure why you are getting the error messages you posted, but perhaps this provides a work-around for the time being. + seth
