Hello,
We've been trying to use FSL voxelwise confound option to remove physiology confound. We notice the confound regressors produced by Feat or Pnm is the always the same regardless different subject fMRI data. We're not exactly sure how Feat and Pnm handle these voxelwise confound, but we thought the confound regressors would be based on the signal from individual fMRI data. Is that right? Or is the physiological regressors only depend on physiology signal and slice order? If so, why Pnm would require fMRI data in the input?
Thank you,
Pei
