Hi Christian,
Sorry, I still have questions to need your kind helps.
From the group ICA output results, sometimes I can see the last
component has negative variance proportion value, like -1.06% of
explained variance; -0.61% total variance. I am confused with it. Would
you please explain it for me?
In addition, group ICA also has a simple plot and a boxplot that show
the relative effect size across the different sessions/subjects, which
come from the values in the first column of matrix s..txt I guess. My
questions are what the physics meanings of these values is? How to
compute the values and they have units? What does negative value mean?
Sorry to bother you so much.
Any help would be great appreciated!
With best regards,
Weiming
