Oh that's ok, glad you are back. I will speak with colleagues and check into the full model regression option. In the mean time I did my best to rework the python script with your suggestions. Unfortunately I am getting this error repeatedly. We have the updated python script in our abin so I am confused why this is occuring.

--regress_censor_extern: Command not found.
-regress_stim_files: Command not found.
-regress_errts_prefix: Command not found.
.

Here is the actual adapted script I used:

afni_proc.py -dsets ${subj}_${sess}_vr_zp4_cardnudg_e2a_FWHM+tlrc. \
-out_dir /Volumes/Spock_HD/Dane_FC/FC_DATA_Task1/ICN_Runs \
-blocks scale regress
-regress_censor_extern $censorfile/${subj}_${sess}_autocensor_AC3VC_pre-moco.1D \
-regress_polort 3 \
-regress_apply_mask ${subj}_s4_vr_zp4_cardnudg_e2a_amsk+tlrc. \

-regress_local_times \

-regress_stim_times 2 $stimdir/${subj}_Weak_stim4b.1D -regress_stim_label 2s 'Weak' \
-regress_stim_files 3 /Volumes/Motion_Pre-moco/${subj}_${sess}+orig_vr_motion.1D'[0]' -regress_stim_labels 3 'roll' \

1. what did you mean in regards to response 1." Pass it all sessions at once. If you do not, the EPI will not be aligned across runs. The runs do not need to be of the same length. " ?

2. do I need to run 1dBandpass on the motion regressors called upon in this script or will afni_proc take care of it?
