Hi Rick,

Yes, I expected that the BOLD responses vary across the brain. Therefore I used TENT function. And I also think that TENT is more suitable for event-related stimulus right? And my stimulus is event-related not blocked.

For GLT, I have tried without including rest_time.1D following your suggestion. And to make sure I myself do the right analysis, may I write down the steps I did as follows?:
So for the underlay, I chose the "fitts" results (Actually no matter what is ok right?)
And for the overlay, I chose results from "bucket", named "stats" to see the GLT results.

For the functional color overlay controls:
OLay - chose lefthand#0_Coef
Thr - chose lefthand#0_Tstat

Then to see the clustim results, I chose cluster size of pthr=0.01 and alpha=0.05, which is 80 voxels from NN1_2sided.1D file.
Then click Report to see the activated regions. And the listed clusters are the real responsive ones, right?

I'm sorry that perhaps my questions are quite boring and stupid. But I just found I can not ask for help except in AFNI's forum...
Really appreciate for your reply Rick.


Best regards,
Tracy
