stScales: Compute the ST-scales of a protein sequence

In Peptides: Calculate Indices and Theoretical Physicochemical Properties of Protein Sequences

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.
