bwa-mem2-dna-aligner
by jaechang-hits
"Fast short-read DNA aligner for whole-genome, whole-exome, and ChIP-seq alignment to a reference genome. BWA-MEM2 is the 2× faster successor to BWA-MEM; outputs SAM/BAM with read group headers required by GATK. Produces primary alignments with supplementary records for chimeric reads.
