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.

Hi everyone,

I was wondering if there is an option in 3dDeconvolve or some other AFNI program that can calculate goodness of fit for GLM. For example, one can use TENT functions instead of a single BLOCK to model the response to a task, and would like to consider whether the TENTs or the BLOCK work better by comparing their goodness of fit. I haven't seen this is performed anywhere, and there might be an obvious reason why people don't or rarely do this. The comparison of goodness of fit seems more straightforward for each voxel. What about for the entire brain. I would appreciate if someone can please explain.

Thanks a lot,
Duong
