CTDD: CTD Distribution (CTDD)

Description

This function computes the distribution part of CTD. It calculates fifteen values for each property. For more information, please check the references.

Usage

CTDD(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

This function returns a feature matrix. The number of rows is equal to the number of sequences and the number of columns is 15*7.
