40 De novo clustering of features.
|
|
|
41 --------------------------------
|
|
|
42
|
|
|
43 Given a feature table and the associated feature sequences, cluster the
|
|
|
44 features based on user-specified percent identity threshold of their
|
|
|
45 sequences. This is not a general-purpose de novo clustering method, but
|
|
|
46 rather is intended to be used for clustering the results of quality-
|
|
|
47 filtering/dereplication methods, such as DADA2, or for re-clustering a
|
|
|
48 FeatureTable at a lower percent identity than it was originally clustered
|
|
|
49 at. When a group of features in the input table are clustered into a single
|
|
|
50 feature, the frequency of that single feature in a given sample is the sum
|
|
|
51 of the frequencies of the features that were clustered in that sample.
|
|
|
52 Feature identifiers and sequences will be inherited from the centroid
|
|
|
53 feature of each cluster. See the vsearch documentation for details on how
|
|
|
54 sequence clustering is performed.

|
|
56 Parameters
|
|
|
57 ----------
|
|
|
58 sequences : FeatureData[Sequence]
|
|
|
59 The sequences corresponding to the features in table.
|
|
|
60 table : FeatureTable[Frequency]
|
|
|
61 The feature table to be clustered.
|
|
|
62 perc_identity : Float % Range(0, 1, inclusive_start=False, inclusive_end=True)
|
|
|
63 The percent identity at which clustering should be performed. This
|
|
|
64 parameter maps to vsearch's --id parameter.
|
|
|
65
|
|
|
66 Returns
|
|
|
67 -------
|
|
|
68 clustered_table : FeatureTable[Frequency]
|
|
|
69 The table following clustering of features.
|
|
|
70 clustered_sequences : FeatureData[Sequence]
|
|
|
71 Sequences representing clustered features.
