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

Thank you for your answer!

1) It was 100% linked to the resolution, now it is more about 20min/run...

2) 2.800003 2.799999 2.799998 80 80 42 280 Rest_BOLD.nii.gz

2) It is 24 for me

3) mALFF should be a voxelwise value... so I don't understand this statement:
"Also, to calculate mALFF, the result is strongly dependent on the mask used. Is there a way with afni_proc to add this mask in -regress_RSFC?"

If I understand correctly, mALLF is the ALFF (calculated voxelwise) divided by the average fluctuation of the brain. If you use a brain mask, it should scale differently the results, right?

4) thank you! I was not aware of that! I will try that.

4b) It seems that bandpass improve the results in monkey and since I want to compare my results to them I think I should do it. I know that there is a lot of debates around that in humans. If you have a good paper to suggest around that matter, I will be really interested in reading it. > Just find the papers in the discussion on 3dAmpToRSFC =)

5, 6, 7, 8) thank you for this advice! I will change that!
