Hi all,
I have questions in the pre-processing and PPCA stages?
1. Data - Is the mean removed per image or per voxel before doing PPCA? I
see that "Estimating data smoothness" message appears before doing PCA.
What kind of smoothing is done (Spatial or temporal)? Is there a way to turn
off that option.
2. PPCA - Only PCA results in the 2nd reduction stage are saved. Is there a
way to get the PCA information (whitening) in the first data reduction stage of
the temporal concatenation method?
Thanks for the great software.
