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 aFnIeRs :)

For events-related design, do I have to specify actual event duration for basis function? Say I have stimulus A for 4s and B for 0.5s. I am thinking of using BLOCK(4,1) for A, GAM for B, or maybe BLOCK(0.5,1)???. My understanding is that the user-specified durations are (internally) used a boxcar/square wave to convolve with the underlying basis function.
