Hello AFNI experts,

I am interested in applying either a high pass or bandpass filter from afni in another program, and am wondering whether there is a way to save the design matrix (possibly a .1D file?) for this filter as a series of columns that can be regressed out of my timeseries in another software.

I would use AFNI’s 3dTproject, but I want to perform the “non-aggressive” denoising used by ICA-AROMA (which performs partial regression, making signal and noise components compete for variance so that shared variance in noise components is not removed).
So ideally, I hope to get columns for a filter I can append to the matrix for my other nuisance regressors to simultaneously perform partial regression and filtering in FSL using the fsl_regfilt command.

Any guidance here will be greatly appreciated. Thank you!
Best,
Will
