ced2go is expected to work with DST files if one specifies a -v flag to choose DSTViewer.
This modifies the default template steering file ced2go-template.xml to use DSTViewer instead of the default one.
If the user specifies the detector geometry with a flag -d, the default template steering file is changed to ced2go-template-DD4.xml, which does not work with DST files.
The ced2go-template-DD4.xml looks very different and incomplete compared to ced2go-template.xml.
It doesn't have the DSTViewer processor defined and always uses the default CEDViewer, thus also ignoring the -v flag completely.
Note that a user is required to define the detector geometry with a flag -d; otherwise, the code exits.
But it doesn't work with dd4hep geometry and requires obsolete Gear geometry files.
Additionally, a user should know where the MarlinStdRecoViewerDST.xml is located.
Using the iLCSoft environment, I managed to find it, but using key4hep, I did not.
Another workaround is to add a DSTViewer processor to the user's steering file.
How to fix
Add -v flag support to the ced2go-template-DD4.xml like in the ced2go-template.xml.
An even better option would be to use only one general template file and not have two.
They don't seem very different, so compressing them into a single steering file should be straightforward.

is completely unusable forDST
files.Workarounds

P.S.
Is there a viewer option for mini-DSTs?
