Hi Mahsa,
Sorry for being slow. We are teaching at the AFNI
bootcamp this week.
The resolution you are seeing is that of the data,
and it should match what is seen in the afni GUI
(unless you tell the GUI to oversample it). Your
data seems to be at 2mm^3.
If you want to resample it, it might be enough to
resample the anatomy:
3dresample -input T1.nii -rmode Cu -dxyz 1 1 1 -prefix T1.1mm.nii
The Color and Thr volume indices can be changed by
clicking on the labels to the right of those words.
To specify your own range, turn off "autoRange" by
clicking on the toggle box just to the left of that
text. Then specify whatever range you want instead
of 10000.
