RE: import two session data
Updated: I was just able to get
the pop-up instructions about setting duration for the
condition. They were not showing up before. I think
this will solve it.
...
I am having a related issue. I have two sessions per subject; session 1 is condition A and session 2 is condition B. However when I click to highlight the appropriate session for each condition, it carries the same selections to the other condition, so I can never specify different sessions for each condition. How do I do this? Or can you point me to an example of a condition file to upload? Thanks!

Hi Alfonso,
I have tried your way to import data but I have two SPM.mat (because I did the first level analysis separately for each run).When I setup for 2 session and import the second run ,it overwrite the first one's functional image.And 2 session I set before turned to 1 session again. So I can't import two SPM.mat in one project.
Is it a appropratiate way to directly do the paired t test between two condition using the first level result(the fisher's z score) If I only want to know whether the difference of the connectivity of two ROI between two condition is significant ?
Thank you very much for your help!

It is perfectly possible and acceptable to compare two conditions defined in two separate runs/sessions. To do that you typically simply associate (in the Setup->Conditions tab) each condition with one specific session (and leave the 'onsets'/'durations' fields for the rest of the sessions empty). In your case it will be simpler to simply/directly import the SPM.mat files into the conn toolbox and that will import all of your specific conditions and block orderings so you do not have to retype those values. To do this click on the Setup->Import button, then select the SPM.mat files (one per subject), and click on the 'Done' button, and the toolbox will import all the relevant information from there.
Let me know if this helps and/or if you run into any issues

Hi experts,
I have a problem in import data from SPM.mat. I have two session for each subject and each session have several conditions. I want to compare one condition in first session with another condition in second session. Because I random the block order(onsets of each condition differ between subjects), it will take a long time for enter the onset for each subject manually. I have already do the first level analysis in SPM, so I want to import the SPM.mat .
But I can not define two sesseion in conn GUI and can not find the batch in conn batch manual. and I want to know is that acceptable to compare two condition in two separate run directly?
Appreciate any help, Thanks a lot for your tim
