Hi Alfonso,

I ended up reverting back to the previous version to add my ROIs - however I followed your instructions and tried loading in a test atlas into version 17 and got the same error.

The command which('rex') points to the correct release of conn.

When I click the Check ROI labels option in Setup.ROIs I see that all 132 of the ROI labels appear:

I tried debugging the code by pausing the execution at line 763 and it seems that the labels are not being read correctly by the rex function. Vermis10 is inserted for all of atlas labels, which causes the error.

I'm absolutely stumped! I've attached my conn_*.mat file.  I hope you can reproduce it!  I can also try on another machine and get back to you.

PS I'm using MATLAB 2016a
