Dear Alfonso,

I have completed the first-level analyses in my CONN project for SBC. However, when attempting to proceed to the second-level analyses, I encountered an error. Please note that all the NII files from the first level have been saved.

Could you please provide any assistance or hints on how to resolve this issue?

Here is the full error message:
