  1. Other than using more RAM on short reads to REF-2, Mora consistently used fewer resources than AugPatho2 and was substantially faster. Time cannot be directly compared between the Mora/AugPatho2 and Kraken2/Clark as they require the output from one of the initial aligners. Clark has an asterisk to signify that had errors in building the REF-2 database, which resulted in less resources used. CPU time and other information can be found in Additional file 1: appendix Table A.4. All algorithms were run with 8 threads on a Google cloud virtual machine instance of type c2-standard-60
