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

You can use negative times in TENT or CSPLIN -- this is allowed for just the situation you are in. You might want to do TENTzero(-12,12,13), which should give one "knot" (break-point for the TENT) every 2 seconds, with the "zero" meaning that the first and last points in the TENT-modeled HRF will be set to zero -- thus you will have 11 basis functions.
