Hi Hari, To get the data that you need from Agilent you need to register with their earray site here: https://earray.chem.agilent.com/earray/ And then once you can log in, you should be able to find files with the information you need. The Agilent site can be surprisingly difficult to use, but the data is usually in there. Then once you have the data you will want to look at this vignette: http://www.bioconductor.org/packages/2.10/bioc/vignettes/AnnotationDbi /inst/doc/SQLForge.pdf Marc On 08/07/2012 10:45 AM, Hari Easwaran wrote: > Thanks Jim.
