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

In that paper, they use a method similar to the one used in our 3ddelay program, that computes the maximal correlation of shifted time series. You may want to take a look at that program. Also consider the approach used here by Bellgowan, Saad and Bandettini:

Also we have recently published a paper using 3dNLfim, our non-linear fitting program, to compute latencies among HRF curves using a different model that worked well with our data. Many of the details are in the supplementary materials.
