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

Hello pt,

Thank you for these clear explanations!
Typically, the range of censored time point fractions is around 5 on 275-time points. One subject is around 34 but it never goes up to 20%.
I am a little bit concern by the raw ALFF and fALFF images produced with this analysis, to my knowledge, high ALFF values are essentially around the DMN. However, I do not observe that here.

assuming you are using the recommended 3dLombScargle+3dAmpToRSFC with your censored time series
==> yes I do,
However, I bandpassed my BOLD images during afni_proc.py, does it affect the results to re-bandpass with 3dAmpToRSFC?
Just to be extra sure, the file from afni_proc.py to input into 3dLombScargle is: censor_subj_combined_2.1D?

Thanks a lot!
