Hi Steve,

Thank you for your help even if I do not understand your answer completely.

First, the definition file does not create anything. All it does is set the workspace variables. It is precisely the file called by RUN on line 56.

Secondly, I checked with the function WHICH and I do not have another RUN function neither as EVALIN.

Finally I compared the workspaces of a successful call with a non-successful call and they are identical. The only solution I have at the moment is to restart Matlab every time.

Thanks again
