after temporal concatenation group ICA, use of melodic_mix time courses to derive
individual resting networks and voxelwise comparison of these between two group we see
robust focal effects between the conditions.
My concern/hypothesis now is that 'simple' lower general network fluctuation amplitudes in
one of the conditions leads to this (especially as the major nodes are affected).
Question: is there a chance to use the melodid_mix file to derive an amplitude measure for
each subject? E. g. by using FFT power? Or is the melodic_mix file changed by normalisation
steps that no absolute amplitude information is contained any more?
Would you have an alternative suggestion on how to define the average percentage BOLD
fluctuation of a resting network?
Thanks a lot again!
