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

I don't think you need a specific reference to justify your modeling approach. ANOVA simply means that the data have a structure of two or higher dimensions. Such dimensions can be subjects, groups, conditions, etc. Even though ANOVA is often adopted for population-level modeling in neuroimaging with subjects as one dimension, it does not mean the methodology can only be used with subjects as one dimension. In this case, you have conditions and trials as two dimensions in your regression model.

>> I would also be happy to read through the math behind this contrast to understand how it calculates the F-stats here!

Essentially the model remains the same, but the difference regards various ways to parameterize those conditions. See if the following is helpful:
