## shapiroAcceptor

### Description

Shapiro's score of acceptor site (range is from -13 [intron] to +1 [exon]) is: 100 * ((t1 - l1)/(h1 - l1) + (t2 - l2)/(h2 - l2))/2, where t1 is the sum of the best 8 of 10 percentages at positions -13 to -4, l1 is the sum of the lowest 8 of 10 percentages at position -13 to -4, h1 is the sum of the highest 8 of 10 percentages at positions -13 to -4, t2 is the sum of percentages at positions -3 to +1, l2 is the sum of the lowest percentages at positions -3 to +1, and h2 is the sum of the highest percentages at positions -3 to +1

### Usage

### Arguments

`reference_fasta` | vector of strings or DNAStringSet of reference splice list
`target_fasta` | vector of strings or DNAStringSet of fasta to score
