Hi,
I ran a 3dDeconvolve script (see below) on each of our subj +orig maps, with TENTs and the -iresp option. The resulting bucket file shows for each of my three regressed conditions sub-bricks for 7 timepoints. I also have three separate output files from the -iresp options.
I am not sure what output files to use when running t-tests comparing for example two groups on one condition. My goal is to look at significant differences in volumes of group activation for a condition, and then apply the usual cluster threshold using AlphaSim and Clusterize.
Since I have 7 timepoints, do I use all of them and use the bucket file or my t-test, or should I use the output of the -iresp files?

Below is my script. Thanks a lot,
Alessandra
