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 Rick,

Thanks for the explanation. Actually I ran the analysis using BLOCK, but later when I ran the pure deconvolution process to estimate hrf's using CSPLIN, it happened to look that the hrf peaked around 7.5 sec instead of 5 sec. Please check the attached file which has estimated response from early visual cortex close to V1. Also estimated hrf in many other regions showed a small undershoot. So may be for this study it is better to use WAV instead of BLOCK.

-Srikanth.
