How much variance is removed after preprocessing/denoising?
Hello!

Is there a way to measure how much variance is removed from the resting state data after each/all pre-processing steps? Given that the temporal band pass filter and aCompCor both remove degrees of freedom, I am curious about what percentage of the variance in the original signal remains after all of these signals are regressed out. I would also like to see if there is a population-specific differences in variance removed as well. 

Thank you!

Hello!

I just wanted to follow up on this question since I'm still unsure about it.
