Hi, thanks for your reply and for the example. We originally had the other components but had left out the 'anat_has_skull no' option. Once we added that to the afni_proc.py script we were able to run the generated script without errors. When we added that option, it removed the following lines from the subject proc script which seemed to be causing the error.
# warp anat follower datasets (affine)
# catenate all transformations
cat_matvec -ONELINE
\
anatQQ.101A_WARP.nii.gz
\
3dAllineate -source anatSS.101A+orig
anatQQ.101A.aff12.1D > warp.all.anat.aff12.1D
\ \ \
-master anat_final.$subj+tlrc
-final wsinc5 -1Dmatrix_apply warp.all.anat.aff12.1D
-prefix anat_w_skull_warped
Thanks again!
