seqcomplement - Calculate complementary strand of nucleotide sequence

Syntax

SeqC = seqcomplement(SeqNT)

Arguments

SeqNT Enter either a character string with the characters A, T (U), G, C, and ambiguous characters R, Y, K, M, S, W, B, D, H, V, N, or a vector of integers. You can also enter a structure with the field Sequence.

Description

SeqC = seqcomplement(SeqNT) calculates the complementary strand (A-->T, C-->G, G-->C, T-->A) of a DNA sequence and returns a sequence in the same format as SeqNT. For example, if SeqNT is an integer sequence then so is SeqC.

Example

Return the complement of a DNA nucleotide sequence.

s = 'ATCG';
seqcomplement(s)

ans =
