Dear SPM list,
I am quite new in SPM 99 and I have some question sabout SOA in a fMRI
design...
we did a study with the followng conditions
movement right hand without medication
movement left hand without medication
movement right hand with medication
movement left hand with medication
in sum 240 scans, d.h.:
10 rest 10 activ 10 rest 10 activ 10 rest 10 activ per condition:
4 x 60!
Also scans per session = 240
So how do I have to specify the modell
number of conditions = 4 ???????? (Whats with the rest condition???)
SOA Scans for active 20 ???????? (there a in sum 60 scans...?????)
First trial scan = 10 ????
epoch length for active scan = 10 ????
I tried a lot, but it doesn' t work in a correct way, so many thanks for
the help!!!
Boris
