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,

We are triggering data acquisition off of our subject's pulse to
avoid artifacts due to motion coupled to the cardiac cycle. This
leaves us with data acquired at irregular timepoints. Stimulus events
are timelocked to data acquisition, so these, too, are timed
irregularly.

I know I can create a model timeseries for these data using waver's
tstim option, but that time series will then be atregular tr and not
at the times our data were actually recorded. Is there a way for
waver to also output the data at irregular times. Or is there a
workaround for my problem that I fail to see?

Thanks for any ideas on this,
Kai
