Hi,
I was wondering if anyone could help - I have some questions about the output (report) from MELODIC (concat-ICA)
First, for each IC there is a graph showing the time-course of the component (Temporal mode): this covers 360s, which makes sense (180 time points x TR 2s), except that I can't figure out where the time-course comes from? Is it the time-course of one subject (and if so, which one?) or an average time-course? When I click the graph I get a text file with 7 columns (360 lines)...but I input 6 subjects, and none of these columns is an average of the other six...
Second, the sessions/subjects mode: I didn't input a design matrix at this stage (I went for the dual-regression approach) but there are F and p values reported. Do these refer to the fit of the mixture model? And the contrasts to the gaussian model and 2 gamma model?
Third, at the top of the screen for each component the % of explained variance and % of total variance are reported. What variance do these refer to?
Thanks for your help!
Best wishes,
Emma
