seqrcomplement

Calculate reverse complement of a nucleotide sequence

Syntax

SeqRC = seqrcomplement(SeqNT)

Arguments

SeqNT

Nucleotide sequence. 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

seqrcomplement calculates the reverse complementary strand of a DNA sequence.

SeqRC = seqrcomplement(SeqNT) calculates the reverse complementary strand 3' --> 5' (A-->T, C-->G, G-->C, T-->A) for a DNA sequence and returns a sequence in the same format as SeqNT. For example, if SeqNT is an integer sequence then so is SeqRC.

Examples

Reverse a DNA nucleotide sequence and then return its complement.

s = 'ATCG'
seqrcomplement(s)

ans =
CGAT
