Figure 3From: Considerations when using the significance analysis of microarrays (SAM) algorithmFC effects on the brain aging data set: SAM analysis at various fold changes using the brain aging data set (11 old samples and 10 young samples) while scoring genes with a q-value of <0.01 and FC>1.5. We used both the full data set and the reduced data set suggested by the authors. (A) The full data set. (B) The reduced data set (20% "present" calls by D-chip").Back to article page
