When I use Mac command line to run this:

/Applications/Slicer.app/Contents/MacOS/Slicer --launch ResampleScalarVolume -i linear -s 1,1,1   
$CoregPath/Coreg\_$MRI.nii.gz   
$CoregPath/CoregResamp\_$MRI.nii.gz

It always switches to the ‘Welcome’ model automatedly.  
Does anyone know how to use the command line, comes into ‘ResampleScalarVolume’ model?

The `--launch` option is used to run another program in Slicer’s environment (e.g. paths and settings).

You want to use the `--python-code` option like this to set the module:

./Slicer-4.13.0-2021-06-28-linux-amd64/Slicer --python-code “slicer.util.selectModule(‘SegmentEditor’)”
