Hi Alfonso,

I read many of your posts in which you mention that CONN uses CompCor for the denoising step. I was wondering what exactly is CompCor doing, does it simply regress out the WM and CSF, or does it refer to the whole regression of confounds we list in the denoising step (eg WM, CSF, motion regressors)? I suppose band-pass filter and detrending are not part of the CompCor algorithm?
My understanding is that CompCor generates principal components (PCs) that can be used as covariates in a GLM. Is this automatically done in CONN, where can we find these PCs? And how can we use CompCor information when analyzing resting state connectivity (without a GLM)?
Thank you,
Ben
