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

Hey,
I have removed the first 5 volumes, have applied slice time correction, and have processed the data with Pestica/Slomoco (version 5) to correct for physiological cardiac and respiratory noise and motion. I have also normalized the data to MNI152 using FSL's flirt and fnirt. For ALFF calculation in AFNI, I have not used the -nodetrend flag but I will definitely try that, thank you!

In DPABI, I have used the GUI of DPARSF 5.3 Advanced Edition. I have selected a blank template, loaded the same input as descriped above and have only selected "ALFF/fALFF Band (Hz): 0.01 ~ 0.08".
Best, Melissa
