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, Sam-

You input a non-bandpassed time series to 3dRSFC, and you can get out:
+ voxelwise map of ALFF (single value per voxel), which contains the sum of LFF amplitudes.
+ voxelwise map of fALFF (single value per voxel), which contains the ratio of LFF amplitudes to the full time series' amplitudes.
+ and similarly maps of RSFA and fRSFA, as well as a couple other related parameters.

The LFF range is defined by user, and during that process, the time series are bandpassed, and so one can also output the bandpassed time series, if that is of interest.
