Hi, Dose any one have experience to fix following problem? After downloading and installation of hgu95acdf package, the system still return error message like: AffyBatch object size of arrays=640x640 features (3203 kb) Error in .local(object, ...) : Information about probe locations for HG_U95A could not be found. Try downloading the hgu95acdf package from http://www.bioconductor.org/data/cdfenvs/cdfenvs.html Error in inherits(cdf.env, "try-error") : Object "cdf.env" not found HG_U95av2 chips works fine with same procedures so I guess there is something wrong with the cdf package installation. Thanks! H.Z.

hgu95av2 is include in affy. hgu95a is not. you need to downlaod and install the package from the web page given. -r On Wed, 5 Mar 2003, Zhang, Hongen (NIH/NCI) wrote: > Hi, > > Dose any one have experience to fix following problem? > > After downloading and installation of hgu95acdf package, the system > still return error message like: > > AffyBatch object > size of arrays=640x640 features (3203 kb) > Error in .local(object, ...) : Information about probe locations for HG_U95A > could not > be found. > Try downloading the hgu95acdf package from > http://www.bioconductor.org/data/cdfenvs/cdfenvs.html > Error in inherits(cdf.env, "try-error") : Object "cdf.env" not found > > HG_U95av2 chips works fine with same procedures so I guess there is > something > wrong with the cdf package installation. > > Thanks! > > > H.Z. > > _______________________________________________ > Bioconductor mailing list > Bioconductor@stat.math.ethz.ch > https://www.stat.math.ethz.ch/mailman/listinfo/bioconductor >
