Hi,
Thanks for your reply. When plotted, I did notice that values were similar but scaled differently, and not always in the same direction; just curious as to which I should use.
I was also wondering about how the power spectra are derived for melodic_FTmix. In my text files I always organize by group for group ICA and I'm interested in how the power spectra differ across group (by component). However I noticed that depending on which group goes into the text file first, that group's average power is always much higher across all frequencies compared to the second group; if I run giCA again with the second group going first in the text file, that group now has higher power. If each column of FTmix is organized by subject in the same order that subjects go into the text file, why does this happen?
Thanks!
