Hi

I am sorry to bother you with what probably a quite basic question. I have scrolled through the mailing-list, but I am still a little insecure of how to implement my analysis.

I am analyzing a blocked-designed paradigm where the manipulation is related to increasing load.
I have defined one regressor for each load-condition (control, load 1-4), and want to look at task general activation and activation related to increase of load.
I have defined the T-contrasts for task general activation:(-4 1 1 1 1) where -4 reflects the control condition, and for effect of load i have defined the T-contrast (0 -1.5 -0.5 0.5 1.5).

But is this correct?
Thank you in advance.

Regards
