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)
CP0092730.53752

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.

Final Junction Predictions

Minimum probablilty assigned that no mapped read will start at a given position and strand for junction prediction0.1
Junction allow suboptimal matchesFALSE
Skew score of predicted junction (−log10 probability of unusual coverage evenness) must be≤ 0
Number of bases that at least one read must overlap each uniquely aligned side of a predicted junction≥ 6
