seqrcomplement

Calculate reverse complementary strand of nucleotide sequence

Syntax

SeqRC = seqrcomplement(SeqNT)


Arguments

SeqNT

Nucleotide sequence specified by any of the following: Character vector or string 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.

Description

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

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

Examples

Return the reverse complement of a DNA nucleotide sequence.
