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

Running into an odd circumstance that I can't find documentation of. I have two conditions, with times shown below on an long run (1455 TRs, TR=2 sec).

3 271 452 546 727 995 1089 1357

90 184 365 633 814 908 1176 1270

For whatever reason, 3dDeconvolve seems to not be modeling the later times after about 750ish seconds. Design Matrix link below:

Example

I've tried as both local times and as global times with the same results. Any help would be much appreciated!
