Is it possible to estimate the CanICA model in nilearn in a way that adds another level to the hierarchy, i.e. sessions within subjects? It seems like this was possible in the original CanICA code (https://github.com/GaelVaroquaux/canica/blob/master/canica/main.py) with the two_levels flag. However, there does not seem to be a similar option in the version in nilearn. Is there a way to do this that I am not seeing?
Thanks for all your help!
I’m sorry, this feature is no supported in the nilearn version. It was very seldom used, and removing it lead to simplifying the code.
