CTDD: CTD Distribution (CTDD)

In ftrCOOL: Feature Extraction from Biological Sequences

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.
