LPC_PSSM {PSSMCOOL}

Linear predictive coding feature

Description

This function uses Linear predictive coding algorithm for each column of PSSM Matrix . so in this script lpc function is used which produces a 14-dimensional vector for each column, since PSSM has 20 column eventually it will be obtained a 20*14=280 dimensional feature vector for each PSSM Matrix by this function.

Usage

LPC_PSSM(pssm_name)

Arguments

pssm_name

name of PSSM Matrix file

Value

feature vector of length 280
