predict-fingerprints takes so much time, it is normal?

[ebervilla]

Hi everyone

I just installed q2-qemistree. I am trying to run it using the demo data. I successfully generate the i) fragmentation trees and ii) molecular formulas. However, when I try to predict the fingerprints, it takes so much time running and never ends. For example, I left it running overnight. is this normal?

Thank you so much for your help,

Cheers, Eber
