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 Lisa,

For creating unit vectors of the time series, you might consider
what @compute_gcor does:

3dTnorm -polort 0 -prefix OUTPUT INPUT

The default scaling is the L2 norm, setting the sum of squares
equal to 1. If instead you want the standard deviation, then there
is a factor of sqrt(NT-1) to scale in. Maybe I should consider
adding such an option...
