Thank you very much for reviewing the values.
Yes, I used a blur of 4 via the afni_proc.py. Based on my protocol, my voxels for my epi volumes are 2x2x3mm and for my anat volumes are 1x1x1.
For the mask, I came across a few threads indicating the use of 3dmask_tool. I created and ran the following code below on a few participants and this seemed to work well. Is there a reason that the group mask is constructed at 70% overlap and not a higher overlap value?
3dmask_tool -input [subjects results folder] full_mask*tlrc.HEAD -prefix mask_group.7 \ -frac 0.7
Thank you very much,
Tamara
