Hi - I should be able to answer this - but I'm afraid I'm not quite sure
exactly what you are asking, in your second paragraph?
Cheers.

Hi - what is your rfMRI protocol? It might be that you're right that the
difference is in the preprop - but my first guess might be that - if the rfMRI
data is not as high quality as HCP rfMRI data - it might not be good enough to
reliably drive MSMALL?
Cheers.

Hi - yes IIRC it's only the demeaning that is important - the scaling of the
regressors makes no difference to the output from the deconfounding.
Normalising SD is a "sane" step in such processing in general, and sometimes is
of value (depending on what outputs one is interested in wrt the
Hi - we calculated them in order to estimate the volumetric group maps.
However AFAIK we didn't bundle them in the PTN release.
You can easily get them though by regressing node timeseries into 4D
FIX-cleaned data.
Cheers.

Hi -
In the most recent PTN release, all node maps (melodic_IC.dtseries.nii) created
with group-ICA are sign-flipped (if necessary) to have positive maximum
voxel/greyordinate, and then rescaled so this peak is 1. The values of other
voxels across the map will vary from node to node, and the
Hi - well we had quite a few other confounds too - and didn't dig deep into
their correlations with the imaging measures (though the deconfounding overall
does have quite a strong effect as can be seen in the different results
presented in MegaTrawl).
One obvious reason for not rushing to do

Hi - not in general, no. The data has already had drift (very lowest
frequencies) removed, and I personally am not a believer in lowpass filtering
clean data.

Hi - this order:
ff{1}=sprintf('%s/%d/MNINonLinear/Results/rfMRI_REST1_LR/rfMRI_REST1_LR_Atlas_MSMAll_hp2000_clean.dtseries.nii',SUBJECTS,subID);
ff{2}=sprintf('%s/%d/MNINonLinear/Results/rfMRI_REST1_RL/rfMRI_REST1_RL_Atlas_MSMAll_hp2000_clean.dtseries.nii',SUBJECTS,subID);
HI - looks like maybe the fieldmap inputs are not setup correctly?
Cheers.

Hi - yes, there's no reason why successful FIX denosing (like we get in HCP
data) should remove valid high-frequency signal.
