I use the following command to generate the script for analysis of our dataset.

afni_proc.py -subj_id s1sm.align \
-dsets Data/s1sm?+orig.HEAD \
-blocks volreg blur mask scale regress \
-do_block align tlrc \
-copy_anat Data/s1_t2+orig \
-tcat_remove_first_trs 2 \
-volreg_align_to last \
-volreg_align_e2a \
-volreg_tlrc_warp \
-tlrc_base TT_EPI+tlrc \
-regress_stim_times stimes.sm.1D \
-regress_stim_labels SM \
-regress_basis 'BLOCK(15,1)' \
-regress_censor_motion 1.0 \
-regress_est_blur_epits \
-regress_est_blur_errts \
-remove_preproc_files \
-execute

However, once I look at the statistics I get activation all over the place, even outside the brain (see attached screenshot). Did I miss any step in the script? Or are there any steps I need to take after running the analysis? I could also submit the origninal dataset, if you want to take a look at it.

Thanks for your help,

Tim
