Hi! Has someone used retroicor (retroactive correction of physiological noise; Glover at al. 2000) with Freesurfer? I would like to create nuisance regressors for EPI data based on cardiac and respiratory signals. The AFNI version of retroicor produces slice-based regressors, and I am not sure how to use them in Freesurfer. Suggestions for alternative implementations would also be appreciated. Thanks! Caspar
