Hi Attia, If you have the mapping from Affymetrix, you can make a package following the instructions in the vignette here: http://www.bioconductor.org/packages/2.8/bioc/vignettes/AnnotationDbi/ inst/doc/SQLForge.pdf Marc On 10/19/2011 03:21 AM, Jan Van der Goten wrote: > Hi Attia, > > The annotation file of the miRNA 2.0 array is available on the Affymetrix website. > http://www.affymetrix.com/support/technical/other/miRNA- 2_0.annotations.20101222.zip > Greets, > > Jan > > -----Original Message----- > From: bioconductor-bounces at r-project.org [mailto:bioconductor- bounces at r-project.org] On Behalf Of attia fatima > Sent: woensdag 19 oktober 2011 10:54 > To: bioconductor at r-project.org > Subject: [BioC] annotation db for miRNA_2 Array > > Hi there > Can any one guide me to annotation database for GENE-CHIP miRNA_2 Array of > affymatrix,or another way annotations for this Chip.Thanks > Attia > > [[alternative HTML version deleted]] > > _______________________________________________ > 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 > > _______________________________________________ > 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

Oops sorry, I should have read that more carefully. A miRNA package will not be possible (using the tool that I pointed to) unless you actually have a mapping to relevant genes. The problem is more difficult because your probes are not measuring genes (which are units that annotations are more traditionally attached to). To get annotations for a platform like this will either require an association with genes or some other source of prior knowledge about these miRNAs.
