filter_best_hits | R Documentation |
This function aims to retrieve the best blast hits for each query sequence
by filtering a blast_tbl
using the following criteria.
A best hit is defined as (fulfilling all three critaria):
maximum alig_length
: only the hit having the longest alignment length is retained.
qcovhsp >= min_qcovhsp
: only hits that have a query coverage of at least min_qcovhsp
are retained.
maximum bit_score
: only the hit having the highest bit-score is retained.
filter_best_hits(blast_tbl, min_qcovhsp = 50)
blast_tbl |
a BLAST table generated with |
min_qcovhsp |
minimum query coverage of the hit in percent |
