If you run tkmedit-sess, then open the overlay configuration window, then advance the time point to the delay you want. Otherwise, you can create a contrast where you just look at the delay you want. To do this, run mkcontrast-sess with -setwdelays and specify 0 for all delays and 1 for the delay you want to see.

That's the problem Doug. I have already generated the FIR model but how can I show the sig MAP for one "particulat time point". What are the other ways?

Hi Shahin, there are several ways that you could do it. The one that immediately comes to mind is to use an FIR and then test for a difference at a particular post stimulus time point. doug On 04/10/2013 03:54 PM, SHAHIN NASR wrote: Hi, I want to generate a map to show the significant difference between HRF undershoot (negative peak of activity) between two conditions independent from the positive peak. Is there anyway, to generate this map?
