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

Thank you for your response. Sorry, I misphrased my question. I don't really want just the HRF-- I would like the anticipated BOLD response (essentially, an HRF convolved with event delta-functions and scaled by a beta-weight) and a "cleaned" time series for each brain voxel. Presumably I can generate the BOLD response with an AfNI utility, but I had hoped it might be stored somewh

Hello,
I'm trying to sort out some interesting behavior in my fMRI data and I'd like to look at just the "fit of interest": what AfNI thinks the Hemodynamic response should look like, without any of the polynomials to remove motion, noise that changes over time, etc. In other words, I'd like to get the model that is used to select the beta value in the "#RUN_Coeff&q

Hello all, in FSL there is an implementation for TFCE (see here for a technical report and here for the related paper).
