fit dispersion is the ratio of the variance to the mean for the negative binomial fit. It is =1 for Poisson and >1 for over-dispersed data.

Junction Skew Score Calculation

reference sequencepr(no read start)

Exported0.02853

pr(no read start) is the probability that there will not be an aligned read whose first base matches a given position on a given strand.
