Hello AFNI experts,

I did the tlrc transformation using @auto_tlrc command. Since, the tlrc'ed anatomy had a low resolution, I performed tlrc transformation again by usage 2 of @auto_tlrc command. The output was clean and good. I had to perform resampling of the functional dataset using adwarp. After the adwarp operation, the functional images overlays with the anatomical tlrc in a very different manner.

The following commands were executed:

@uto_tlrc -base TT_avg152T1+tlrc -input anat+orig -no_ss -ok_notice

@auto_tlrc -dxyz 1 -apar anat_at+tlrc. -input anat+orig. -suffix test

3drename anattest+tlrc anat+tlrc

3drefit -orient RAI *rest*.HEAD
3dDetrend -del 2 -expr \"Pleg(1,(t-$NT)/$NT)\" -prefix rest_3d rest_3dreg+orig.
adwarp -apar anat+tlrc. -dpar rest_3d+orig. -resam Li -prefix rest-norm -dxyz 3

I am also attaching the dataset for your reference.

Thanks
Hema
