R: Compute the T-scales of a protein sequence

tScales {Peptides} | R Documentation

## 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.
