[Icatb-discuss] SPM design matrix for multiple regression

[Nikola V. <n.v...@me...>]

Hello,
I'm a researcher working at the University of Groningen. At the moment I 
am trying to analyze some resting state data and I'm struggling to 
understand how I should set the sorting matrix for a multiple 
regression. The question is that I have 18 subjects, 2 sessions per 
subject one with rTMS and one without. I was wondering if there is a way 
to sort the components by how much they are correlated with the time 
course of the stimulation target point, but not on a group level as TMS 
has different effects on the BOLD signal in different subjects. I 
thought of using a temporal multiple regression, but I got stuck at 
setting the SPM design matrix which would contain my individual 
time-courses (actually the first eigen vector for the whole target point 
roi, but still a n(volumes) x 1 vector)Which images need to be loaded in 
the SPM.nscan? How does the design matrix look like? If you can just 
point me at a publication that would be already great.

Best regards
