How to get the 4 modalities

[yahoo17]

I have some questions and could you please to help me.
4 modalities has been mentioned in the paper, they are joint, bone, joint motion, and bone motion.

when I check your code, I only find the code of two flag,

  vel: True
  bone: True

Could you tell me how to get the four modailities with correct config?

And whether using 'ensemble.py' and use the four modalities as input can get the best result in your paper?
