Description

Hi,

I was looking through your TICA features calculation, it looks like you are computing phi instead of psi.

https://github.com/microsoft/timewarp/blob/44dca8474cb6182458830677763261cffccfaac4/utils/tica_utils.py#L26-L28

Shouldn't it be _, psi = md.compute_psi(trajectory) instead of _, psi = md.compute_phi(trajectory) ?

Best regards,
Florian

Research direction

Start in utils/tica_utils.py at lines 26-28 and inspect how the TICA angle features are calculated. Compare the current phi call with the issue's proposed psi call. Done means the calculation uses the intended angle and the project's available checks pass.
