Dear Jenna,

That was a bug which was fixed a couple of years ago (in older version you could disregard subjects in ROI-to-ROI analyses only in the second-level analysis step), updating CONN to the latest release should fix this and allow you to proceed without that subject.

Hope this helps

Dear CONN community, 

I am running first-level analyses (ROI-to-voxel and ROI-to-ROI) on a dataset of 820 subjects, each with three scans longitudinally (although not every subject has a scan at every timepoint). During the pre-processing steps, I have left out one subject (721) because their scans were too distorted. I am now finishing up the first-level analyses. I specified that CONN should leave out subject 721 from the first-level pipeline by unclicking "All subjects" before running the step, and manually selecting all subjects except for subject 721 (while leaving "all Conditions" checked). Step 1/3 and 2/3 of the first-level analyses (i.e., ROI-to-voxel and ROI-to-ROI) run just fine, but on step 3/3 (i.e., setting up second-level ROI analysis), I get the error below. It seems that CONN is not recognizing that I want to leave out subject 721 once it gets to step 3/3. Has anyone encountered this error before and can advise on how to proceed?

Thank you kindly!

Jenna
