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

I'm pretty sure this is what 3ddot does with the -demean option. Except without the bells and whistles. But everyone likes bells and whistles, right?

Maybe you're just asking them to add more bells and whistles to 3ddot?

To be more specific, I am under the impression that demeaning and then taking the dot product of two vectors is equivalent to calculating the Pearson's r of the two vectors. If this is incorrect I'd like to know... ;)

thanks!
