AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

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

Regards
