seqrcomplement

Calculate reverse complementary strand of nucleotide sequence

Syntax

SeqRC = seqrcomplement(arguSeqNT)

Description

SeqRC = seqrcomplement(arguSeqNT) calculates the reverse complementary strand of a DNA or RNA nucleotide sequence. The return sequence, SeqRC, reads from 3' to 5' and is in the same format as SeqNT. For example, if SeqNT is a vector of integers, then so is SeqRC.

Examples

Return Reverse Complement of DNA

Return the reverse complement of a DNA nucleotide sequence

s = "ATCG";
seqrcomplement(s)

ans =

    'CGAT'

Input Arguments

SeqNT — Nucleotide sequence

character vector | string scalar | row vector of integers | structure

Nucleotide sequence, specified as one of the following values:

• Character vector or string scalar with the letters A, 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.
