tScales {Peptides}

Compute the T-scales of a protein sequence

Description

T-scales are based on 67 common topological descriptors of 135 amino acids. These topological descriptors are based on the connectivity table of amino acids alone, and to not explicitly consider 3D properties of each structure.

Usage

tScales(seq)

Arguments

seq

An amino-acids sequence

Value

The computed average of T-scales of all the amino acids in the corresponding peptide sequence.
