How to opt out of non-rigid registration?

[shclair]

Alright- I do not know much about Python, but we are trying to see if S2P will work for our data! So I am going through step by step to see what it does, but I am running into an error. It might be that I don't fully understand but if anyone can help that would be great.

S2P suggests that if rigid registration does not work, then you can run nonrigid registration- which leads me to think that non-rigid registration should not be happening automatically. however the default is always set to "1" nonrigid: (bool, default: True) whether or not to perform non-rigid registration, which splits the field of view into blocks and computes registration offsets in each block separately. https://suite2p.readthedocs.io/en/latest/settings.html

However, when I try to set it to 0 (false, which I might assume means do not run), then suite2p cannot finish due to an error

Is anyone familiar with this? Is it possible to opt out of non-rigid registration? What am I misunderstanding?
Thank you!
