Greengenes dataset link is broken

[mchowdh200]

Hi all,
It seems that the download link for the Greengenes dataset is no longer present in the google drive folder. It's not a huge deal since I can just try to get it directly from the source, but I thought I'd let you know. On that note, is there any sort of preprocessing/QC done on the sequences in the dataset that I should be aware of? I'm interested in using this data to reproduce some results.
