Hi everyone, I'm interested in using the FIX-denoised data, and am currently looking at the extended package, as I'm interested in the volumetric data.
I'm wondering whether the motion parameters have already been regressed out from the FIX denoised rfMRI_REST1_LR_hp2000_clean.nii.gz? I'm assuming yes, that the FIX denoised actually already deals with this by separating the motion-related noise into a component and filtering that out of the signal? I assume so based on the following snippet from the manual describing FIX-ed data: "As part of this cleanup, we also used 24 confound timeseries derived from the motion estimation (the 6 rigid-body parameter timeseries, their backwards-looking temporal derivatives, plus all 12 resulting regressors squared — Satterthwaite et al., 2013). The motion parameters have the temporal highpass filtering applied to them and are then regressed out of the data aggressively, as they are not expected to contain variance of interest." Am I correct? Has white matter and/or cerebrospinal fluid been regressed already from the FIX denoised fMRI timeseries? Has physiological data (“rfMRI_REST1_LR_Physio_log”) already been regressed from the FIX denoised data? Any pointers would be much appreciated.
