Dear List, could anybody help to convert affy probes for the S.aureus chip into gene names. i am using Limma to generate a topTable for my comparisons but cannot get an output with more info than affy probe IDs.

Hi Marcos, We already have probe and chip packages provided for that affy chip here: http://www.bioconductor.org/packages/devel/data/annotation/ And you can easily use the AnnotationDbi package to make an annotation package from the resources at affy. You can see relevant documentation here in the pdf called " SQLForge: An easy way to create a new annotation package with a standard database schema.": http://www.bioconductor.org/packages/release/bioc/html/AnnotationDbi.h tml Please let us know if you have further questions, Marc On 01/12/2012 07:58 AM, Marcos Pinho wrote: > Dear List, > > could anybody help to convert affy probes for the S.aureus chip into gene > names. i am using Limma to generate a topTable for my comparisons but > cannot get an output with more info than affy probe IDs. > > Regards, > > > > _______________________________________________ > Bioconductor mailing list > Bioconductor@r-project.org > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor [[alternative HTML version deleted]]
