I have seen that there is currently no option to spatially smooth data in fMRIPrep, although the ICA-AROMA-paper suggests to apply smoothing (6mm FWHM) before using it (https://doi.org/10.1016/j.neuroimage.2015.02.064). Does somebody know if there is a reason why it is not implemented?
I would like to make use of ICA-AROMA in the pipeline but I don’t know where to employ smoothing. Does anybody have suggestions?
Thank you for your help!
