hello
I would like to know how to get the time-course of activation for a VOI. I am able to get values from the matlab window, but I do not know if they have to be adjusted.
In our design, each subject were scan 4 times (2 control and 2 treatment runs) and each run as 6 trials of 3 events each (anticipation, pain stimuli, evaluation).
When I extract the activation at a specific volume, do I need to adjust for the event pain for exemple? When I do not adjust, I get values around 100-200. Alternatively, do I need to substract values ajusted for the contrast of interest minus the values adjusted for the remaining? (note that the baseline are not model in my design)
Thanks for your input
Daniele
