+Reference-based chimera filtering with vsearch.
+###############################################################
+
+Apply the vsearch uchime_ref method to identify chimeric feature sequences.
+The results of this method can be used to filter chimeric features from the
+corresponding feature table. For additional details, please refer to the
+vsearch documentation.
+
+Parameters
+----------
+sequences : FeatureData[Sequence]
+    The feature sequences to be chimera-checked.
+table : FeatureTable[Frequency]
+    Feature table (used for computing total feature abundances).
+reference_sequences : FeatureData[Sequence]
+    The non-chimeric reference sequences.
+dn : Float % Range(0.0, None), optional
+    No vote pseudo-count, corresponding to the parameter n in the chimera
+    scoring function.
+mindiffs : Int % Range(1, None), optional
+    Minimum number of differences per segment.
+mindiv : Float % Range(0.0, None), optional
+    Minimum divergence from closest parent.
+minh : Float % Range(0.0, 1.0, inclusive_end=True), optional
+    Minimum score (h). Increasing this value tends to reduce the number of
+    false positives and to decrease sensitivity.
+xn : Float % Range(1.0, None, inclusive_start=False), optional
+    No vote weight, corresponding to the parameter beta in the scoring
+    function.
+threads : Int % Range(0, 256, inclusive_end=True), optional
+    The number of threads to use for computation. Passing 0 will launch one
+    thread per CPU core.
+
+Returns
+-------
+chimeras : FeatureData[Sequence]
+    The chimeric sequences.
+nonchimeras : FeatureData[Sequence]
+    The non-chimeric sequences.
+stats : UchimeStats
+    Summary statistics from chimera checking.
