What is does BWA-MEM2 is the new version of the bwa-mem algorithm in bwa. It produces alignment identical to bwa and is ~1.3-3.1x faster depending on the use-case, dataset and the running machine. The algorithm is robust to sequencing errors and applicable to a wide range of sequence lengths from 70bp to a few megabases.

This tools build a reference index for the bwa-mem2 galaxy tool.
