Dear Andrew,
 
many thanks for this beautiful tool and your help.
 
It seems I have a similar Problem to the one Matt posted in 2013: I get this error message "Design Matrix not found or inconsistent", even though I cannot see any reasons why the design Matrix and correlation Matrix should not fit. I checked the number of lines, and the connecticity matrices appear correct and don't contain NaN.
 
I attach both matrices; any help would be greatly appreciated.
 
Thanks,
Christian
