This will require our technical team to get in touch with the technical people managing your license software. Please write to [[Technical support | technical support]] so that we can arrange this for you. | ||

The wrapper script named <code>run_cosplot.sh</code> will not work as is on our servers because MATLAB assumes that some libraries can be found in specific locations. Instead, we provide a different wrapper script called <code>run_mcr_binary.sh</code> which sets the correct paths. | ||
