Usage: qiime feature-table filter-features [OPTIONS]

  Filter features from table based on frequency and/or metadata. Any samples
  with a frequency of zero after feature filtering will also be removed. If
  no value(s) are provided for max_frequency and/or max_samples, they will
  default to infinity (i.e., no maximum frequency and/or sample filter will
  be applied).

  The where parameter takes a SQLite WHERE clause. See the table filtering
  tutorial for additional detail:
