fastapairs output file
 
The fastapairs output file contains alignments in FASTA format, one alignment for each hit (accept). Each consecutive pair of sequences is one pair-wise alignment. Within each pair, the query is first, then the target, with gaps inserted as needed. Here is an example with two hits:
