Why the value of seqclass_max_absdiff can greater than 2?

[LDS-axel]

The value of seqclass_max_absdiff, the difference between the the predicted probability of the reference allele and the alternative allele for a regulatory feature, is calculated by (palt−pref), and should have a range from 0 to 2. However, few results in Sei-framework show value greater than 2.

The sequence class scores are not difference from two probabilities. They are projections of 21907 probabilities predicted by Sei - so that are not bounded to 0-1. Thus the abs value of the difference is not bounded by 0-1 as well.
