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

Hi-

So, you have bandpassed your data, so presumably your time series are just LFFs now. That means that fALFF cannot be estimated, since there is not the "full" spectrum to be calculated for the denominator of the ratio.

For ALFF, you mentioned in an email that your data were also censored when going through your pipeline. At present there isn't a function for estimating ALFF when the data have been censored (because there are missing time points). I had started a function that could potentially do this, but will have to revisit it.
