R: Compute the ST-scales of a protein sequence

stScales {Peptides} | R Documentation

## Compute the ST-scales of a protein sequence

### Description

ST-scales were proposed by Yang et al, taking 827 properties into account which are mainly constitutional, topological, geometrical, hydrophobic, elec- tronic, and steric properties of a total set of 167 AAs.

### Usage

    stScales(seq)

### Arguments

`seq` | An amino-acids sequence

### Value

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