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

Not precisely. There are some programs for inter-subject analysis using non-parametric analogs to t-tests and ANOVAs (3dWilcoxon, 3dMannWhitney, 3dKruskalWallis). These operate on ranks, not via permutation tests.

It is also possible, via 3dfim+, to use Spearman (rank) correlation in the time series analysis of a single task. This ability, however, was purely experimental, and I don't recommend it.

None of these programs use the variance smoothing approach of SnPM.

Your question is somewhat vague, and it would be better to ask about the capabilities you want for your tasks at hand, rather than make a query like "can AFNI do X?" without context.
