Example uses the QIIME2 Moving Pictures tutorial dataset

What is checked: ID column naming · duplicate or empty sample IDs · column count consistency · #q2:types directive presence and validity · declared vs. detected column types · missing value rates · column name formatting · downstream tool compatibility for diversity, longitudinal, composition, and classification analyses.

Files are processed entirely in-browser — no data is uploaded or stored. For full QIIME2 metadata format documentation see docs.qiime2.org/tutorials/metadata.
