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:

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

Hello AFNI experts,

We used 3dRegAna to identify brain activity that changed according to a specific behavioral pattern. The data we are working with are brain activity associated with different time periods in a within-subject experiment (i.e., activity associated with memories that are 1 hour, 1 day, 1 week, and 1 month old). For the model component, we used the following command where column 1 is our predicted pattern of change. Columns 2 through 22 code for individual subjects (full command at end of post). 
-model 1 : 0 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 \
-bucket 2 Regression_RemoteTime_confident_ForgettingCurve \
-brick 0 coef 1 Time_Estimate \
-brick 1 tstat 1 Time_TStat

We examine the tstat associated with the first column. This approach has worked well for us. 
Our question is the following. QUESTION: How can we look at the effect of time period while using column 1 as a nuisance covariate? That is, we want to detect brain regions where activity changes across time periods while regressing out the effects of forgetting. In this case, we would leave the first column intact. How should we setup the model to test this effect?  

Thank you!
Catherine

Here is the full 3dRegAna command I am using to model.
