Hi everyone
I apologize for the silly question but I am confused on how to setup the afni_proc script to analyze my finger tapping fMRI task. The task is basically a subject tapping with all 4 fingers 4 times on the left, then the right hand, then pause 20 seconds, and then repeat another time.
I used the GAM function and I am only able to visualize the left side of the brain results . This was my script:

# afni_proc.py -subj_id test -script proc.test -scr_overwrite -blocks tshift \
# align tlrc volreg blur mask scale regress -copy_anat \
# /media/server2/crypto4/backup/intraop/volunteer/t1.nii -dsets \
# /media/server2/crypto4/backup/intraop/volunteer/pre.nii \
# -tcat_remove_first_trs 0 -volreg_align_to MIN_OUTLIER -volreg_align_e2a \
# -volreg_tlrc_warp -blur_size 8.0 -regress_stim_times \
# /media/server2/crypto4/backup/intraop/volunteer/stims.txt \
# -regress_stim_labels stims.txt -regress_basis GAM \
# -regress_censor_motion 0.3 -regress_apply_mot_types demean deriv \
# -regress_motion_per_run -regress_reml_exec -regress_compute_fitts \
# -regress_make_ideal_sum sum_ideal.1D -regress_est_blur_epits \
# -regress_est_blur_errts


thank you a lot again
