Hi,
I want to try a new method to analyze my data. Here is my paradigm:
Rest period...Task...Rest...Task...
Task period is 30s. I want to analyze with rest period out of my EPI.
So, I created another EPI using TRs when subject is performing task only.
Total task time=240s
I added first rest period of 30s in the EPI also.

Now, I am trying to run TENT(-10,240,101) but it is giving me error of insufficient data points.

Can someone help me? What am I doing wrong here ?

Thanks
