RE: only load a subset of seeds/rois in ROI-to-ROI or graph theory results explorer?
Hello,
1) What I typically would do in such a case is to define a new first level analysis and only select the subset of ROIs/seeds that you are interested in. This would result in a second level analysis which will only show connectivity between the subset that you are interested in.
2) Again, I believe a simple answer is to define different first level analyses with different seeds of your choice. You can switch between them in the GUI by a simple click. This would be helpful if you have different kinds of questions that you need to answer within the same broader analysis framework.
3) I think the merge utility should do exactly that; I haven't tried this feature myself so cannot confirm but I think that's what would happen. You can confirm that by checking a few file names in the merged project. When you hover over the images in the Setup tab (anatomical or functional), Conn will display the full path to that image. This can help in identifying which subject is which.
Hope this helps

Dear CoNN users,
First and foremost, thank you very much for this incredible toolbox.
I usually run through a batch script the default conn pipeline with a lot of subjects and a lot of seeds/ROIs (>600). I have several questions:
1) After preprocessing, I usually like to investigate second-level analysis only in a subset of seeds/ROIS (say 10-20). However, no matter which contrast I enter or which subset of seeds I select in the second-level tab, every time I enter the ROI-to-ROI explorer or the graph-theory results explorer, it takes an insane amount of time only to load the initial panel, since it loads/processes all 600 seeds. Is there a way to tell CoNN to open ROI-to-ROI or graph-theory results explorer only considering a subset of seeds?
2) Alternatively, after I have preprocessed and first-leveled all subjects, can I remove for second-level purposes a subset of seeds? (say for a particular study I am only interested in 20 seeds from the 600 I have preprocessed).
3) Finally, I know it has been asked but just want to confirm how to merge two conn projects in conn18a. Both projects were run through exactly the same batch script and the same conn version, but one has say 50 subjects and the other 20. How could I come up with a single project of 70 subjects? Will subjects1...50 be the ones from the first project and subject s51...70 be from the second project?
Thanks a lot in advance!!
