Art.m overload?

I am using the conn toolbox to analyze fMRI data. I have posted this question in a forum there but have yet to get a response. Using Conn, I am able to get through all of the steps of imaging analysis without an error, but when I try to open the results viewer, I get the attached error. I do not know when during the imaging process this error is occurring and am not sure how to figure it out and I do not understand what "art.m overloaded by file" (the last line of the error code) means. I read the overload class functions page, but I still do not understand it. Can anyone offer some insight?

In that code, if valid<=Nr1 is not true for any entry, then Nlabels(valid<=Nr1) would be empty, and that would not be permitted for accumarray(). I speculate that you have an empty ROI.

With regards to the art.m please show us the output of

which -all art

"art" is not part of any Mathworks toolbox, so it might not matter for your purposes if it is overshadowed, but it might matter. You might need to use pathtool to move Artifacts_Detection_Tool to further down in the path.
