Hi,
I am running through an analysis with afni_proc.py and getting a problem with one subject that I run. The afni_proc.py command is the following:

afni_proc.py -subj_id sub10_ffa \
-dsets FFArun*+orig.HEAD \
-blocks despike tshift align tlrc volreg blur mask scale regress \
-copy_anat anat+orig \
-align_opts_aea -cost lpc+ZZ \
-tlrc_base TT_N27+tlrc \
-volreg_align_to MIN_OUTLIER \
-volreg_align_e2a \
-volreg_tlrc_warp \
-blur_size 4.0 \
-regress_local_times \
-regress_stim_times sub10_overstim/FFArun*.txt \
-regress_stim_labels Face House \
-regress_basis 'BLOCK(16,1)' \
-regress_opts_3dD \
-gltsym 'SYM: Face -House' \
-glt_label 1 F-H \
-regress_est_blur_errts \
-execute

And the text output is:

subject ID : sub10_ffa

I checked the QC file generated by proc.py, the result is the attached image 1, it’s abnormal compared with other subjects. It was normal to use the same script to analyze the data of other subjects.I have checked everything I can think of and cannot seem to find where this error is coming from.

I also added “-regress_censor_motion 0.2, -regress_censor_outliers 0.1, -regress_motion_per_run, -regress_apply_mot_types demean deriv” to the script.This subject’s data result did not do well either,the result is the attached image 2.

Thank you very much for any assistance,

Dan
