Dear NBS forum, 

Hello everyone, I am a student who is currently trying to learn how to use NBS for my research project. I have two groups (22 in total), and I am attempting to perform a two-sample t-test with two covariates to assess group differences in structural connectivity. However, when I run the analysis, NBS returns an error indicating that the connectivity matrix cannot be found or that the connectivity matrices are inconsistent.

I was wondering whether there might be an issue with my connectivity matrix text file, or whether there is another issue causing the error. I have attached my connectivity matrix list (.mat file), design matrix, and contrast file for reference. 

Thank you so much for your time.
