AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

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 \
-dsets \
	$directory_deoblique/Run_deoblique+orig \

-volreg_pvra_base_index MIN_OUTLIER \
-mask_segment_anat yes \
-mask_segment_erode yes \
-regress_compute_fitts \
-regress_polort 2 \
-regress_bandpass 0.01 1 \
-regress_anaticor \
-regress_ROI WMe CSFe \
-regress_apply_mot_types demean deriv \
-regress_motion_per_run \
-regress_censor_motion 0.3 \
-regress_censor_outliers 0.1 \
-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!
