Hello experts,
I wold like to ask for advice on setting up an analysis.
I have a 2x2 experimental design with two unbalanced groups fMRI data.
The questions are -
(1) in the control group, which areas are associated with factor A, factor B, and factor A*B, and
(2) In the regions identified from Q1, does the measure in the experimental group differ from the control group for factor A

Hello experts
The group_mask+tlrc from the afni_proc.py script (below) is too large (pic attached: underlay anat_final, overlay group_mask). I would like to create a common group mask for the study for later group comparisons.
My questions: 1) Is there something I can do to get a better mask; 2) should I use the GM mask to create a common mask for group comparisons instead.
Thank you.

Hi
I ended up doing that - running multiple scripts to finish it faster.
However to update my previous message- on my machine, subs running with 48 threads were completed 5-10 mins faster than those on 12 threads (~38-40 vs 45-50 mins).

Hi
It seems fine now. Each subject is taking about 45 to 60 mins. The number of threads doesn't seem to make a difference. I ran a few subjects each with 12 and 48 threads and it takes about the same time.
The registration in a bunch of these subjects has turned out pretty well. But thanks for the tip about the -giant_move; will surely be handy.

I have updated the binaries and set threads to 15. I will post an update once a subject is done.
After the update 3dQwarp -hview shows ++ OpenMP thread count = 15
This is the output for 3dinfo -extent for a couple of random subjects

Hello experts
I ran @sswarper on a subject [@sswarper $inputT1 $subid -deoblique]. It took about 11-12 hours for a single subject. The second subject is also taking just as long.
The T1 image dims are 174 x 213 x213 (res is 1 x 0.94 x 0.94 mm).
afni -ver is slightly outdated AFNI_17.2.07
But the script running on a server with 96 cpus and I set OMP_NUM_THREADS=48
I have the terminal out
