hi,
i am having trouble analysing some data i have in my data set i have 8 runs
(each aquired seperatly on one subject) each run = off/on/off/on/off/on/off/on
(each for 30secs)and each on period was a set of different stimuli (eg-abcd)
and the order was in one of four orders (ie each order was repeated 2wice)
i did what i thought was the correct first level analyses ie i analysed each
run seperatly (4EV's - off =240 and phase (210, 150, 90, 30 respectivly for
each EV/block)) and did 3 contrasts on each. but i want to look at each of
these contrasts over the 8 runs not just on their own ie-look at the data as a
whole over 8 reps.
how would i go about doing such a higher level analysis, or have i gone about
doing the first level analysis wrong?
any help would be great, i am sure this is a standard procedure but i am
banging my head agaisn't a wall:)
andy
