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 charactersR,Y,K,M,S,W,B,D,H,V,N.
Row vector of integers from the tableMapping Nucleotide Integers to Letter Codes.
MATLAB^®structure containing aSequencefield that contains a nucleotide sequence, such as returned byemblread,fastaread,fastqread,genbankread,getembl, orgetgenbank.

Description

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

Nucleotide inSeqNT	Converts to This Nucleotide inSeqC
`A`	`T`or`U`
`C`	`G`
`G`	`C`
`T`or`U`	`A`

Examples
