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
