FPSSM {PSSMCOOL}

D-FPSSM and SF-PSSM feature vectors

Description

This function produces list of two feature vectors named D-FPSSM and S-FPSSM which then used by FPSSM2 function to construct feature vector of length 100 for each pair of proteins which then used for protein-protein interaction prediction in each dataset.

Usage

FPSSM(pssm_name, hk = 20)

Arguments

pssm_name

name of PSSM Matrix file

hk

a parameter that indicates which amino acid alphabet must be used

Value

two feature vectors of different length which is used in later steps.
