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 Rick,

Yes, they do contain pre-SS volumes. I usually get rid of the first 10 or so TRs when I'm working with resting-state data, but I didn't want to remove too large of a chunk from the first block. However, I should probably remove 3-4 TRs instead of 2, as you say.

I've adjusted the stimulus timings, so that, e.g., if the first one is at 7 seconds, I subtract 4 seconds (=2 TRs) and end up with 3 seconds.

3dinfo -tr does return 2.0.

Ah, yes, I'm too used to resting-state pre-processing.. It seems like using a high-pass filter would be preferable!
