Problem

You try to process an image but GraXpert process stop with Error code #1 displayed in PixInsight console.

Solution

Most of the time this is due to the fact that process cannot start GraXpert in command line mode.

First thing to do is to check that last release of GraXpert application is properly installed on your system.

You can get application from GraXpert Github.

Then you can open a console window on your computer and launch the application from command line.

Name of the application depends on your operating system. All is described in our Quick User Guide but in short:

• Windows: graxpert
• macOS: /Applications/GraXpert.app
• Linux: graxpert

If it doesn't work, ensure you have the application in your default system path or setting "Custom App. Path" properly set in process (checkbox on bottom right).

Good to know

On Linux, application is usually installed in /opt/bin/ and you have to set parameter "Custom App. Path" or create a symbolic link in /usr/bin/

You can create a link with following command: sudo ln -s /opt/GraXpert/GraXpert /usr/bin/graxpert
