Hello all, I have recorded 80 volumes in a block design experiment with a TR of 6 seconds where 3 seconds are silence, the machine is silence, and the other 3 seconds are used for the adquisition. In the 3 seconds of machine silence I present a stimulus, 0.5 seconds later of the begins of the silence, with an aproximated duration of 1.5 seconds What is the best strategy for processing this data?
