Predicates
A number of predicate or query functions are supported for sequences, allowing you to check for certain properties of a sequence.
BioSequences.isrepetitive — Functionisrepetitive(seq::BioSequence, n::Integer = length(seq))Return true if and only if seq contains a repetitive subsequence of length ≥ n.
BioSequences.ispalindromic — Functionispalindromic(seq::BioSequence)Return true if seq is a palindromic sequence; otherwise return false.
BioSequences.hasambiguity — Functionhasambiguity(seq::BioSequence)Returns true if seq has an ambiguous symbol; otherwise return false.
BioSequences.iscanonical — Functioniscanonical(seq::NucleotideSeq)Returns true if seq is canonical.
For any sequence, there is a reverse complement, which is the same sequence, but on the complimentary strand of DNA:
------->
ATCGATCG
CGATCGAT
<-------Using the reverse_complement of a DNA sequence will give give this reverse complement.
Of the two sequences, the canonical of the two sequences is the lesser of the two i.e. canonical_seq < other_seq.
