Correlations with p < 0.001 and nstrains ≥ 12 are computed and saved in advance and this tool retrieves from that table.
Alternatively you can compute correlations on-the-fly with more flexibility (but must be 3 or fewer expression data sets).
A "number of unique objects examined" summary is available with "on-the-fly" computation.
The large number of eligible probeset data instances increases the liklihood of strong mathematical correlations occurring by chance.
 DPV = data point variance filter.
Stricter settings will omit instances where data points have more variance amongst animal replicates within a strain/sex group.
To see DPV hover your mouse pointer over the p value.
