QIIME 2 has succeeded QIIME 1 as of January 1, 2018. QIIME 1 is no longer officially supported, as our development and support efforts are now focused entirely on QIIME 2. For more information about what this means, see our blog post: QIIME 2 has succeeded QIIME 1.
QIIME 1 users should transition from QIIME 1 to QIIME 2. If you're new to QIIME, you should start by learning QIIME 2, not QIIME 1.
The QIIME 1 website can be found at http://www.qiime.org. For related software projects and data, see biocore.
