vhseScales: Compute the VHSE-scales of a protein sequence
Description
VHSE-scales (principal components score Vectors of Hydrophobic, Steric, and Electronic properties), is derived from principal components analysis (PCA) on independent families of 18 hydrophobic properties, 17 steric properties, and 15 electronic properties, respectively, which are included in total 50 physicochemical variables of 20 coded amino acids.
Usage
vhseScales(seq)
Value
The computed average of VHSE-scales of all the amino acids in the corresponding peptide sequence. Each VSHE-scale represent an amino-acid property as follows:
VHSE1 and VHSE2: Hydrophobic properties
VHSE3 and VHSE4: Steric properties
VHSE5 to VHSE8: Electronic properties
Arguments
seq
An amino-acids sequence
