seqcomplement

Calculate complementary strand of nucleotide sequence

Syntax

SeqC = seqcomplement(SeqNT)


Arguments

SeqNT

Nucleotide sequence specified by any of the following: Character vector or string containing the lettersA, C, G, T, U, and ambiguous characters R, Y, K, M, S, W, B, D, H, V, N. Row vector of integers from the table Mapping Nucleotide Integers to Letter Codes. MATLAB® structure containing a Sequence field that contains a nucleotide sequence, such as returned by emblread, fastaread, fastqread, genbankread, getembl, or getgenbank.

Description

SeqC = seqcomplement(SeqNT) calculates the complementary strand of a DNA or RNA nucleotide sequence. The return sequence, SeqC, is in the same format as SeqNT. For example, if SeqNT is a vector of integers, then so is SeqC.

Nucleotide in SeqNT	Converts to This Nucleotide in SeqC
A	T or U
C	G
G	C
T or U	A

Examples

Return the complement of a DNA nucleotide sequence.
