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 Sam,

Yes, censoring with ZERO leaves them as all-zero volumes.

Censoring is done so that unreliable time points do not affect the results. When running a correlation analysis on those residuals, all-zero volumes would still not affect the results.

Inserting artificial data does not seem preferable. That would likely add artificial weight to the time points neighboring censored ones, and would not add any information to the data. Note that we do not interpolate data in the standard linear regression, we simply censor, depriving those time points of impact. The same can be done in a correlation analysis.
