AATP_TPC {PSSMCOOL}

AATP_TPC feature vector

Description

For getting this features which have been used to protein structural class prediction, at first mean of every column in PSSM Matrix is computed to achieve a 20-dimensional vector called AAC.then by combining it with other vector of length 400 called TPC, which is similar to dpc_pssm AATP feature vector of length 420 is obtained.

Usage

AATP_TPC(pssm_name)

Arguments

pssm_name

is name of PSSM Matrix file

Value

list of two feature vectors with 400 and 420 dimensions
