I am trying to annotate a project with BRB array tools. It uses bioconductor annotation packages for this. My chips are the new Affymetrix miRNA 2.0 chips, and BRB requires a mirna20.db file to annotate these. However it cannot fetch it, and I can't find it anywhere. Is this a file that I'd get from bioconductor or affymetrix? Since these chips are new, does it even exist yet? Thanks -Ed

Dear Ed, I had the same problem days ago. The file for miRNA2.0 exists but only for the most recent version of bioconductor (2.8) Try to update bioconductor (and maybe R) and check it again. best, Juan Carlos On 06/30/2011 12:20 AM, Ed Siefker wrote: > I am trying to annotate a project with BRB array tools. > It uses bioconductor annotation packages for this. > > My chips are the new Affymetrix miRNA 2.0 chips, and > BRB requires a mirna20.db file to annotate these. > However it cannot fetch it, and I can't find it anywhere. > > Is this a file that I'd get from bioconductor or affymetrix? > Since these chips are new, does it even exist yet? > Thanks > -Ed > > _______________________________________________ > Bioconductor mailing list > Bioconductor at r-project.org > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: > http://news.gmane.org/gmane.science.biology.informatics.conductor
