I have today uploaded an updated version of Metaxa2 (version 2.1.2). This update primarily improves the memory performance of the Metaxa2 Diversity Tools. The core Metaxa2 programs remain the same as for the previous Metaxa2 versions.

New features and bug fixes in this update:

  • Dramatically improved memory performance of metaxa2_uc
  • Added the 'min' option to the -s flag in metaxa2_uc, which will cause the program to sample the number of entries present in the smallest sample from each sample
  • Fixes a bug that disregarded the level specified by the -l option in metaxa2_si
  • Minor updates and improvements on the manual

The updated version of Metaxa2 can be downloaded here.
Happy barcoding!
