sorry, I meant the differences in scaling across nodes within a subject.
Thanks!

Hi - do you mean differences in scaling across nodes, or within-node
differences across subjects?
Cheers.

Thanks for the reply Stephen,
do you have an idea, how these different amplitudes arise? Do they just
reflect the strength of the BOLD fluctuations within these
regions/components or are they also influenced by other factors like noise
or something? I'm trying to understand if such differences do
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 all,
I was taking a look at the ICA (100) node time series and noticed that some
ROIs have relatively large magnitude while others have a smaller magnitude
(see attached pictures). Can someone explain to me how these differences
arise? In other words, is this the "natural" BOLD activity within
