A Comparative Study of the Impact of G-Stack Probes on Various Affymetrix GeneChips of Mammalia

Table 3

The effect on RMA of removing G-stack probes from probe sets. Subtraction of the original RMA value from the RMA value after removal of G-stack probes gives the quantity 0.5<𝑑≤1.0. Entries are column percentages.
