RE: Different sessions as different conditions?
Hi Gustavo
That is perfectly fine, you can define two different functional sessions as two different conditions. Simply define two conditions (e.g. 'rest' and 'attention') and then associate the 'rest' condition with the first session (in Setup.Conditions select the "rest" condition, then select "session 1" and enter onset "0" and duration "inf", and then select "session 2" and leave the onset and duration fields empty there) and the "attention' condition with the second session (in Setup.Conditions select the "attention" condition, then select "session 2" and enter onset "0" and duration "inf", and then select "session 1" and leave the onset and duration fields empty there).
In general, leaving the onset/duration fields empty (or entering [] -empty brackets- in these fields) for some subject/condition/session simply indicates CONN that this condition is not present in this session/run for this subject.
Hope this helps
Alfonso

Hello everyone!
I've got data from 30 subjects concerning two states (200 volumes each): resting-state and a focused attention state. I intend to study the correlation maps generated in First-Level Analysis. However, I now noticed that two different functional sessions (which would be the 2 states) cannot be defined as two different conditions in Setup.
Is there a way to study these two different states without defining as if it was acquired from different subjects?
