I am carrying out “denoising” (using ICA AROMA) separately on each run of the functional dataset. This denoising produces several components (timeseires) which represent noise for that particular run. I want to include these timeseires as confounds in my 3dDeconvolve model. However, since each run may have different number of confound timeseries, I cannot put them in one single text file with the -ortvec option.
My question is: I there a way to provide multiple confound text files (one for each run) with the -ortvec (or any other) option?
