Hi Matt,

Thanks for your interest. My first suggestion is to check that the number of rows in your design matrix is equal to the number of connectivity matrices in your study (i.e. one connectivity matrix per individual).

Moreover, you may want to delete the two empty new lines appearing after the last row of the design matrix. They may have been interpreted as actual rows of the design matrix.  

It may be that some connectivity matrices were not found or not read correctly. My second suggestion is to check that all the connectivity matrices have been provided and recognized.

If the problem persists, please send me your set of connectivity matrices (assuming you feel comfortable doing that) and I can take a closer look. My email: is azalesky@unimelb.edu.au

Andrew
