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 All,

Another perhaps simple question: Is there a way to account for potential phase offsets during correlation? I guess what I have in my mind is:

- Circular shift each voxel time series until a maximum is reached for the correlation coefficient.

And an output of the max corr. coeff. with the offset phase shift would be great. Tried to do some quick searches in the board and couldn't find anything. Any guidance with this would be very much appreciated. Thank you!

Cheers,
Edwin
