Protein contact map prediction machine learning approach

Question

[akilaramu1998]

Hi,

I am working on protein contact map predictions. Method- Convolution Neural networks I have some doubts of feature extraction methods. In feature extraction methods, we are collecting features from Psi blast, HMM profile etc. I got results by this program. From this result how do I covert to feature vector.or else any methods available for feature extraction for contact map prediction

Is there any specific formats for feature extraction
