Hi,
I'm starting to use MELODIC. While familiarizing myself with this tool, I
ran MELODIC for a subject from the MELODIC gui, then also from the FEAT
gui by selecting "MELODIC" in the Pre-Stats tab. From the same data set,
the MELODIC gui results gave me 48 components; the FEAT gui results gave
me 32 components.
I've confirmed this by running multiple ICAs from the MELODIC gui. They
all yielded 48 components; components from one analysis are very similar
to components from subsequent analyses. I confirmed the results from the
FEAT gui by running just the Pre-Stats. This yielded 32 components similar
to the previous results from running the Full-analysis from the FEAT gui.
Why would MELODIC yield different results depending on which gui it's run
from? Which one is more trustworthy?
Thanks,
