Hi Danielle,
The pipeline sounds good. ICA-AROMA does not include high-pass filtering, so you indeed need to apply this to the denoised data yourselve. Either from the command line by using the -bptf option in fslmaths, or within feat by switching the highpassfiltering option on.
Best,
Raimon

Hi FSL Experts,
I am using the ICA-AROMA package with my task fMRI data. I first ran FEAT pre-processing without temporal filtering (but with smoothing, motion correction, slice timing correction, linear and non-linear registration).
My question is do I now need to run the outputted denoised data with the high pass temporal filtering option on before moving onto first level analyses, or are these artifacts removed with the denoised data (thereby I wouldn't need to run high pass temporal filtering)?
Thanks in advance,
Danielle
