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 all,

I'm working with a dataset with a very large amount of data collected from each participant over many sessions. I'd like to run 3dFWHMx in order to perform cluster correction on an analysis using all of a participant's data, but the errts file produced by 3dREMLfit is hundreds of gigabytes, which is creating logistical issues. Would it be reasonable to use residuals from running 3dREMLfit on a subset of the data (e.g., the first and last session, or maybe the first run of each session) in order to estimate the smoothness of the noise? Or is it pretty important to use all of the data in order to get a faithful estimate?

Thanks!
