GG97 is my name for the default closed-reference database used by QIIME. It is a subset of the Greengenes database (DeSantis et al. 2006) clustered at 97% identity. The filename in QIIME is 97_otus.fasta. I am posting it here because to the best of my knowledge it is not directly available for download; the only way to get it is to install and run the QIIME virtual box.

It is not clear to me which license applies. It
is not included in the QIIME
github repository as far as I can tell.
