Thanks for the explanation.

When adding
-regress_compute_fitts \

to my AFNI proc script, it fails with the following message.

** cannot compute fitts, have 3dD_stop but no reml_exec
** script creation failure for block 'regress'

Any clue what is wrong here? Is something in my script wrong?

...
afni_proc.py \
-subj_id ${subject}_Run \
-out_dir $directory_run/Results \

-blur_size 8.0 \
-regress_est_blur_epits \
-regress_est_blur_errts \
-html_review_style pythonic \
-execute

Update: ok, I see that I had to add
-regress_reml_exec \
when using
-regress_compute_fitts

Another update:
The processing step
++ detrending starts: 153 baseline funs; 2268 time points
is now finally done after around an hour for one subject. Before, even after two or three hours, this step was still not done (when using the standard 34 polorts).
Therefore, it appears that AFNI is much faster using
-regress_polort 2         \
-regress_bandpass 0.01 1

Thanks Rick!
