* p-value is very close to 1.

The number of shared features between the FGA generated sets of hexamers and the exon regulator hexamer sets and the p-value stating the probability of having this overlap or a greater overlap by chance. We highlight the highly statistically significant probabilities. The set D -3mer3 [-80,-1] did not contain position specific hexamers and the set D -4mer2 [-80,-1] contained only 3 position specific hexamers, two of which overlapped with RescueESE set.
