Sorry, I meant to ask what the output file melodic_Tmodes saves. It has as
many rows as there are volumes in my analysis, so it seems to be the time
series, but although the number of columns increases as the number of
sessions entered in the analysis increases, it is not a clear correspondence
between the number of columns and the number of sessions (e.g., 234 columns
for an analysis with 72 sessions that yielded 15 components).
thanks,
Mara
