DDE: Dipeptide Deviation from Expected Mean value (DDE)
Description
This function computes the dipeptide deviation from the expected mean value.
Usage
DDE(seqs, label = c())
Arguments
seqs
is a FASTA file with amino acid sequences. Each sequence starts
with a '>' character. Also, seqs could be a string vector. Each element of the vector is a peptide/protein sequence.
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
A feature matrix with 20^2=400 number of columns. The number of rows is equal to the number of sequences.
