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.

New Junction Evidence

Junction Candidates Tested

Number of alignment pairs examined for constructing junction candidates≤ 1000002459
Coverage evenness (position-hash) score of junction candidates≥ 2≥ 2
Test this many junction candidates (n). May be smaller if not enough passed the coverage evenness threshold100 ≤ n ≤ 5000288

Junction Skew Score Calculation

reference sequencepr(no read start)
NC_0009130.94404

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

optionvalue
Coverage evenness (position-hash) score of predicted junctions must be≥ 3
Skew score of predicted junction (−log10 probability of unusual coverage evenness) must be≤ 3
Number of bases that at least one read must overlap each uniquely aligned side of a predicted junction≥ 1
