Figure 3From: How to decide? Different methods of calculating gene expression from short oligonucleotide array data will give different resultsRelation between signal intensity from MAS 5.0 and RMA. Relation between the signal intensity calculated with MAS 5.0 and RMA software of all probe sets. In general there is a good correlation (r2 = 0.9913), see also table 1. However, variation increased closer to the unity. For example a signal of 4 in MAS 5.0 results in a signal between 4 to 5.5 in RMA on a ln scale.Back to article page
