BitVecAlignmentScore
Description
Calculate alignment score between two bitvectors. Used in bioinformatics-style sequence alignment with match/mismatch scoring.
Parameters
Name | Direction | Description |
---|---|---|
bv1 | in | First bitvector |
bv2 | in | Second bitvector |
match | in | Score for matching bits |
mismatch | in | Score for mismatching bits |
Usage example (from documentation)
int score = BitVecAlignmentScore(&seq1, &seq2, 2, -1);
