Running an external command

Hi,

I read the post on running an external command, but it does not seem to be working.

The command optimuse is located in a subdirectory called optimuse in the plugin folder. It does not seem to be executing. The files are opened correctly (cantus.xml), but the command is not run since no new files are being generated.

Am I overlooking something?

Thanks!
