Hi!

I have a subject with quite a lot of censoring. However, the following afni_proc works well:

afni_proc.py -subj_id sub11 -script proc.sub11 -scr_overwrite -blocks \
despike tshift align tlrc volreg blur mask regress -copy_anat \
/anatomy/sub11.nii -dsets \
/resting_state/sub11_1.nii \
/resting_state/sub11_2.nii \
-tcat_remove_first_trs 0 -align_opts_aea -giant_move -volreg_align_to \
MIN_OUTLIER -volreg_align_e2a -volreg_tlrc_warp -blur_size 4.0 \
-regress_censor_motion 0.25 -regress_bandpass 0.01 0.1 \
-regress_apply_mot_types demean deriv -regress_motion_per_run \
-regress_est_blur_errts -regress_run_clustsim no


Now, I'm trying to understand why it crashes when I try a similar thing, but also regressing out signal from white matter and vent. I get the message of: ** ERROR: total number of fixed regressors (250) is too many for 249 retained time points!
Is there a way to save this subject regressing out wm and ventricles? Here is the afni_proc code that leads to the error:

afni_proc.py -subj_id sub11 -script proc.sub11 -scr_overwrite -blocks despike \

I appreciate any input. Thanks!
