Mismatch_DNA: Mismatch_DNA (Mismatch_DNA)

In ftrCOOL: Feature Extraction from Biological Sequences

Description

This function also calculates the frequencies of all k-mers in the sequence but alows maximum m mismatch. m<k.

Usage

Mismatch_DNA(seqs, k = 3, m = 2, label = c())

Arguments

seqs	is a FASTA file containing nucleotide sequences. The sequences start with '>'. Also, seqs could be a string vector. Each element of the vector is a nucleotide sequence.
k	This parameter can be a number which shows kmer.
m	This parametr shows muximum number of mismatches.
label	is an optional parameter. It is a vector whose length is equivalent to the number of sequences. It shows the class of each entry (i.e., sequence).

Value

This function returns a feature matrix. The number of rows is equal to the number of sequences and the number of columns depends on the rng vector. For each value k in the vector, (4)^k columns are created in the matrix.
