Description

Aligns a subset of Hi-C reads from a CRAM file to a reference genome using minimap2, pipes the resulting alignments through filterfiveend.pl (included), samtools fixmate and samtools sort, outputting an alignment in BAM format.

samtools Documentation

SAMtools is a set of utilities for interacting with and post-processing short DNA sequence read alignments in the SAM, BAM and CRAM formats, written by Heng Li. These files are generated as output by short read aligners like BWA.
