Hi Daniel and Paul,

Below are the commands (including the afni.proc.py commands) that I used on my deobliqued anatomical data and original oblique EPI data for pre-processing. Thank you both again so much for helping me with this!

@Align_Centers -cm \
-base ../MNI152_T1_2009c+tlrc \
-dset T1.deoblique+orig \
-child Encoding1+orig Encoding2+orig

echo $name "Running SSwarper"
@SSwarper \
-input T1.deoblique_shft+orig \
-base ../MNI152_2009_template_SSW.nii.gz \
-subid ${name} \
-giant_move

echo $name "Running afni_proc.py"
afni_proc.py \
-subj_id $name \
-copy_anat anatSS.${name}.nii \
-anat_has_skull yes \
-anat_follower anat_w_skull anat T1.deoblique_shft+orig \
