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

AFNI version
Precompiled binary linux_centos_7_64: Apr 21 2019 (Version AFNI_19.1.04 'Caligula')
This is HCP resting state data, so 0.5/0.72s = .69.

I've been experimeting with afni_proc.py to create a notch filter. I haven't yet been successful. I'm using a simple afni_proc call to examine the generated scripts. The following call generates a processing script that seems reasonable (using bandpass filtering).
afni_proc.py \
-dsets ./*.nii.gz \
-regress_motion_per_run \
-regress_censor_motion 0.2 \
-r

Yes, this is part of an implementation of a pipeline to complete preprocessing of the (minimally preprocessed) HCP dataset that would handle motion, CompCor, GSR. Band-stop is part of this. I understand the suggestion: will use multiple bandpass ranges to implement bandstop. Makes sense. Working on afni_proc script to generate desired pipeline. Thank you.

I am interested in implementing a notch filter in AFNI for resting state fMRI data. The documentation for 3dFourier suggests that you can implement a notch filter by combining the lowpass and highpass options (although an example of doing this correctly is not provided). Therefore, I attempted a notch filter as follows (I'm using AFNI_19.1.04 on CentOS 7).
3dFourier -prefix ${subj}_tas
