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

Rick,

Keep the questions coming!

The images contain five time points corresponding to 15 seconds with a 3 s TR. The first 12 s correspond to the stimulus presentation and the final 3 s the first TR of the rest period.

The IRESP waveforms were generated using 5 TENT functions covering the 15 second period: 'TENT(0,12,5)'

The reason we extended the IRESP function 1 TR beyond stimulus presentation was to have a look at whether the signal rapidly shifted back towards baseline after stimulus offset. Unfortunately we couldn't specify the entire the rest period in the command using 8 TENT functions to model 24 s of signal because we ran into multicollinearity issues.

Vinny
