58 Exclude sequences by alignment
|
|
|
59 ##############################
|

|
|
|
61 This method aligns feature sequences to a set of reference sequences to
|
|
|
62 identify sequences that hit/miss the reference within a specified
|
|
|
63 perc_identity, evalue, and perc_query_aligned. This method could be used to
|
|
|
64 define a positive filter, e.g., extract only feature sequences that align
|
|
|
65 to a certain clade of bacteria; or to define a negative filter, e.g.,
|
|
|
66 identify sequences that align to contaminant or human DNA sequences that
|
|
|
67 should be excluded from subsequent analyses. Note that filtering is
|
|
|
68 performed based on the perc_identity, perc_query_aligned, and evalue
|
|
|
69 thresholds (the latter only if method==BLAST and an evalue is set). Set
|
|
|
70 perc_identity==0 and/or perc_query_aligned==0 to disable these filtering
|
|
|
71 thresholds as necessary.

73 Parameters
|
|
|
74 ----------
|
|
|
75 query_sequences : FeatureData[Sequence]
|
|
|
76 Sequences to test for exclusion
|
|
|
77 reference_sequences : FeatureData[Sequence]
|
|
|
78 Reference sequences to align against feature sequences
|
|
|
79 method : Str % Choices('blast', 'vsearch', 'blastn-short'), optional
|
|
|
80 Alignment method to use for matching feature sequences against
|
|
|
81 reference sequences
|
|
|
82 perc_identity : Float % Range(0.0, 1.0, inclusive_end=True), optional
|
|
|
83 Reject match if percent identity to reference is lower. Must be in
|
|
|
84 range [0.0, 1.0]
|
|
|
85 evalue : Float, optional
|
|
|
86 BLAST expectation (E) value threshold for saving hits. Reject if E
|
|
|
87 value is higher than threshold. This threshold is disabled by default.
|
|
|
88 perc_query_aligned : Float, optional
|
|
|
89 Percent of query sequence that must align to reference in order to be
|
|
|
90 accepted as a hit.
