using copy-feats-to-htk

[Johnson]

hi, i'm new to kaldi. this might be a silly question.
I'm looking for some function that can help me transform MFCC features vector sequences(ark) to a htk file (for further use)
i am recommended to use copy-feats-to-htk function. but I'm not really sure if it really fits my problem, and how does it work.

as I saw the example:
Example: copy-feats-to-htk --output-dir=/tmp/HTK-features --output-ext=fea scp:feats.scp\n" I understand it needs places for output file. but I know(?) that it also needs utterance id(key) in input table, that is, the "feat.scp" (?) corresponding to the htk file name.

is there any clear format for such feat.scp? or can I just put the MFCC.ark file there, whose format is like 
sequence-id1[

...MFCC...

...MFCC...

]

sequence-id2[

...

]
in reality it's something like:
