|
60 Apply the vsearch uchime_denovo method to identify chimeric feature
|
|
|
61 sequences. The results of this method can be used to filter chimeric
|
|
|
62 features from the corresponding feature table. For additional details,
|
|
|
63 please refer to the vsearch documentation.
|
|
|
64
|
|
|
65 Parameters
|
|
|
66 ----------
|
|
|
67 sequences : FeatureData[Sequence]
|
|
|
68 The feature sequences to be chimera-checked.
|
|
|
69 table : FeatureTable[Frequency]
|
|
|
70 Feature table (used for computing total feature abundances).
|
|
|
71 dn : Float % Range(0.0, None), optional
|
|
|
72 No vote pseudo-count, corresponding to the parameter n in the chimera
|
|
|
73 scoring function.
|
|
|
74 mindiffs : Int % Range(1, None), optional
|
|
|
75 Minimum number of differences per segment.
|
|
|
76 mindiv : Float % Range(0.0, None), optional
|
|
|
77 Minimum divergence from closest parent.
|
|
|
78 minh : Float % Range(0.0, 1.0, inclusive_end=True), optional
|
|
|
79 Minimum score (h). Increasing this value tends to reduce the number of
|
|
|
80 false positives and to decrease sensitivity.
|
|
|
81 xn : Float % Range(1.0, None, inclusive_start=False), optional
|
|
|
82 No vote weight, corresponding to the parameter beta in the scoring
|
|
|
83 function.
|
|
|
84
|
|
|
85 Returns
|
|
|
86 -------
|
|
|
87 chimeras : FeatureData[Sequence]
|
|
|
88 The chimeric sequences.
|
|
|
89 nonchimeras : FeatureData[Sequence]
|
|
|
90 The non-chimeric sequences.
|
|
|
91 stats : UchimeStats
|
|
|
92 Summary statistics from chimera checking.
