Possible to convert .txt file to .ark and .scp files?

[K.R]

I been working on building a dnn network for mfcc feature extraction, and now have a model which i want to deploy to  the kaldi framework. 

I've before converterd the .ark and .scp to .txt for training my models, but how do i convert those back to .ark .scp?

The way i converted was using copy-feats. 

../src/featbin/copy-feats scp:${WORKSPACE_SETUP_ROOT}/raw_mfcc_train.1.scp ark,t:- > raw_mfcc_train+s1.txt

Is it possible to convert .txt back to the .scp and .ark files using copy-feats, if so how?

Read "I/O from a command line perspective in the documentation".
That .txt file is the text-form of an archive, which is readable the
same way any archive is. You can do something like
copy-feats ark:raw_mfcc_train+s1.txt ark,scp:foo.ark,foo.scp
