 This modified version (gg_2024_09) was created by [the Systems Genomics Lab](https://github.com/systems-genomics-lab) for use with DeepTaxa. The Greengenes database, downloaded from https://ftp.microbio.me/greengenes_release/2022.10/, was processed as follows:
 1. The original dataset, containing 23,450,269 sequences, was downloaded.

+2. Missing taxonomic classifications were filled with "Unclassified" or derived labels. For each sequence, the taxonomy table's ranks (e.g., domain, phylum, class) were processed sequentially. If a rank was empty or contained only whitespace:
    - If no prior rank had a valid value, the field was left empty.
    - If the previous rank's value included "Unclassified," that value was copied to the current rank.
    - Otherwise, the field was set to "Unclassified_" followed by the previous rank's value (e.g., "Unclassified_Proteobacteria" for a missing class after phylum "Proteobacteria").
