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 Hugo,

Note that by default, duration modulation with dmBLOCK
effectively has some sort of amplitude modulation, in that
it convolves the atomic BLOCK function over the duration
of the given stimulus. As an example, a 10 second stimulus
would convolve to a height of about 5 times that of a 1
second stimulus. But that is what we think of as natural
hemodynamic convolution, not really amplitude modulation.
