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 Floris

One thing you could try is simply using 3dDeconvolve -nodata as you normally would but add in a censor file (via -censor) to censor out "volumes" where no data will be collected. Then, when you actually go to run the GLM on your data you can simply copy in volumes to the data you collected as placeholders when you run 3dDeconvolve so that the regressors generated by -stim_times GAM for instance line up with when the data were collected in time, but these copied volumes are censored out and do not contribute to the results.

I'm sure Rick will have some more ideas!
