i found a model below
when i change use command tool button [Convert model to segmentation node]
i convert the model to segment,it’s well displayed with both model and segmentations
then i save the scene as .mrb file
when i reload the .mrb file , the model displayed well , but the segmentations can’t display,the data seems empty
both model and segmentation can’t display on slice panel
the version 4.11 and 5.02 both has the problem
If I understand well, based on your description, this is not an issue with conversion but with save/load. Please confirm that converting model to segmentation works. Can you reproduce it with data available in Slicer? (For example doing a very simple segmentation on a sample volume, convert it to model and then back)
thank your Pinter,thank you for replay.
the origin operate on slicer is fine.
the model is generated by code by vtkPolyData
when the model is changed to segmentation , the segmentation can’t save/load , can’t operator on most segmentation Effect.
finaly,i found vtkLineSource convert to segmentation has the save/load bug.
