Hello all,
This is my first question in this list and it is about OptSeq2.
I am nee to this command.
In brief, I wish to insert the following but Some of them I could not handle it:
My experiment has three conditions although I will later specify them as one condition:
Moving hand at three different target level ( say 10 20 30). Then I will model them as a one condition and enter the parametric response as a first order polynomial effects.
My design will have two columns : main effect of moving hand and the 1 order.
My contrast will be like this [1 0; 0 1]
This is what I would like to optimize using OptSeq2:
Event design 1) ISI 6 seconds + or - 1.5 seconds ( I could not do this 2) TR 3 3) volumes 150 4) 45 hand movement; 15 at each target level ( I could not do this ) 5) each movement lasts for 3 seconds
I am not sure whether I should use null events or the Period between movement is enough.
Also my main aim is to optimize the best design in terms of detection.
Please any guide or help
Thanks
AS
