I want to do differential expression of Microarray data and then to do meta analysis.do you know R package that do two works?
I heard about the COMBAT batch correction and cross-platform normalization method then you can merge the datasets by means of common ENTREZ identifiers to obtain common space across all platforms.
Dear ED, Hi
Have you tried MAMA ? (manual)
And please check these "Key Issues", too.
Try 'affy' and 'limma' to identify deferentially expressed genes.
"bioMart" for meta analysis.
thank you for a reply,do you know friendly tutorial for this?
You could try these two
From Data import to Normalization in Microarray Analysis using in R (Part I)
Hope it will help.
