Thresholding

AFNI Message Board

I apologize for all my questions here; I also wanted to double-check on the thresholding. If I set up the following model to look at how connectivity changes from Time 1 (T1) to Time 2 (T2) related to change in worry:

-gltLabel 4 ‘Session_Worry’ -gltCode 4 ‘Session : -1T1 1T2 Worry :’ \

Then I’ve been using this output as my overlay, (and using a cluster-based correction), but which output should I select as the threshold in order to visualize the results? The intercept? T2-T1?

Thank you again for the help.

You should use the sub-brick with the label ‘Session_Worry’ that you specified in the command line.

Oh I see, so I should be using e.g. “Session_Worry Z” for both the overlay and the threshold.

Thank you very much for your help.

Use “Session_Worry” for overlay and “Session_Worry Z” for threshold.
