BOLD variance became zero after denoising
Dear CONN users,

In the denoising tab, I found that a couple of participants' data will become % zero variance after denoising. I attached a screenshot on this post. Is this possible if the participant had a lot of movement (the invalid scan has a n=200+) so all the signal has been removed? Or is there something wrong with the dataset itself?

Thank you!
