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

Paul Taylor has seen this reply, and notes that RSFC parameters like ALFF *do* contain units, and hence would be affected by scaling/normalization. The fractional ones (e.f., fALFF) are dimensionless ratios, and so should *not* be affected by uniform scaling.

If you use the "scale" block during processing, then your outputs would have units of BOLD % signal change, and that would seem to be useful and to not require further normalization considerations.
