WebJan 22, 2010 · Abstract. Robust multiarray analysis (RMA) is the most widely used preprocessing algorithm for Affymetrix and Nimblegen gene expression microarrays. RMA performs background correction, normalization, and summarization in a modular way. The last 2 steps require multiple arrays to be analyzed simultaneously. http://web.mit.edu/~r/current/arch/i386_linux26/lib/R/library/affy/html/rma.html
