Is this a thresholding for extreme values?
I often get ICs that are clearly motion artifacts. Since melodic performs motion
correction before doing ICA, I assume that these components are due to the non-
linear effects of motion. Presumably, any linear effects would be removed by mcflirt.
Is that right?
I am interested in removing some of these components from my FEAT analysis. If I
create regressors of no interest, it seems to me that I am reducing the power of my
regressors of interest. Christian had mentioned in a previous message that it's
possible to make a 4D representation of the noise and subtract it out. How can I do
that?
cheers,
jack
