Hi experts,
After using afni_proc.py to preprocess some resting-state fMRI data, there are always some sub-bricks become zeros in the results. I tried several times and got the same results every run. For example, one of the 3dinfo infomation of one subject:
3dinfo -verb errts.S126.tproject+tlrc.
…
– At sub-brick #68 ‘S126.rs.02aptopu[68]’ datum type is float: -48.3584 to 17.7858
– At sub-brick #69 ‘S126.rs.02aptopu[69]’ datum type is float: 0 to 0
– At sub-brick #70 ‘S126.rs.02aptopu[70]’ datum type is float: 0 to 0
– At sub-brick #71 ‘S126.rs.02aptopu[71]’ datum type is float: -19.4341 to 23.5937
…
my code
afni_proc.py \
-subj_id "$i" \
-dsets "$i".rs.02aptopup.nii.gz \
-copy_anat "$i".T1.padded180.nii \
-blocks despike tshift align tlrc volreg blur mask scale regress \

-mask_segment_erode yes \
-blur_size 6 \

-regress_bandpass 0.01 0.1 \
-regress_apply_mot_types demean deriv \
-regress_est_blur_epits \

Could you provide some advice? Thank you!
