Thank you for the responses!
It doesn't sound wrong ;-) However, I'm also not 100% sure want kind of

Exactly, I would like to have a feature selection based on an event, that
could be like the GLM-approach.

My task is a meditation task thus I have few runs with many volumes per
runs and I would like to see the informations carried by the task from a
temporal point of view, so I have a huge amount of features vs very few
runs (six), do you think that repeated random selection could be useful?
Thank you very much,
