Why is my node writer not showing up in the Save dialog ?
You have implemented a loadable module with a new MRML node, its storage node, and the qSlicerNodeWriter needed to save your node on your system file. If the writer is not showing up for your node in the qSlicerSaveDataDialog, it could be one of those following reasons :
- You need to register your writer in the qSlicerIOManager in qSlicerYourModule::setup().
Example: qSlicerMarkupsModule writer registration
- Your node needs to be a sub-class of vtkMRMLStorableNode.
