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

When calculating percent signal change, I calculate a baseline using 3dTcalc
When running 3dDeconvolve, I usually use a censor file, to remove bad, outlier-ish time points (e.g. due to motion, scanner glitch, etc).
What is a conceivable way to use a similar concept (e.g. 1D censor file), to specify the points i want to use for my baseline calculation? (ie i don't want to include outlier timepoints in my average. or for block designs, maybe i'd only want to use average base condition time points for my baseline)
Is there a (easy way) to do this in AFNI? (a -censor option in 3dTcalc would be sweet...)
Is there any mathematical/statistical merit in calculating the baseline differently?

Thanks
