1st level analysis error

Hello NITRC,


First of all, thank you very much for creating such a great program.


I am a complete beginner with CONN. Currently, I am following Andy’s tutorial to check the functional connectivity of one subject. I finished the denoising step and then ran the first-level analysis. However, unlike in the tutorial, the image does not appear on the right side.


I clicked “Done” to try to obtain the image, but I keep getting an error message. I would really appreciate it if you could let me know how to solve this issue.


Thank you very much for your help.
