Hello,

I have pre- and post-intervention scans for 37 subjects, and I have attempted to assign two conditions to the data (pre, post) using the CONN GUI.  However, when running the Setup it gives the following error:
"ERROR DESCRIPTION:

ERROR: Subject 1 does not have any scan associated with condition pre"

...and so on for all the subjects.  I see that, in the conditions menu, I can assign each session-specific scan to a either the pre or post condition, but when I select a different individual scan, it assigns it to whichever condition is highlighted.  

I'm obviously doing something wrong in the interface; could someone help me understand my issue?

Thank you,

Ben
