GTDB-Tk v1.5.0 was released on April 23, 2021 along with new reference data for GTDB R06-RS202. Upgrading is recommended.
Please note v1.5.0+ is not compatible with GTDB R05-RS95.
GTDB-Tk is a software toolkit for assigning objective taxonomic classifications to bacterial and archaeal genomes based on the Genome Database Taxonomy GTDB. It is designed to work with recent advances that allow hundreds or thousands of metagenome-assembled genomes (MAGs) to be obtained directly from environmental samples. It can also be applied to isolate and single-cell genomes. The GTDB-Tk is open source and released under the GNU General Public License (Version 3).
Notifications about GTDB-Tk releases will be available through the GTDB Twitter account (https://twitter.com/ace_gtdb).
Please post questions and issues related to GTDB-Tk on the Issues section of the GitHub repository. Questions related to the GTDB should be sent to the GTDB team.
