Hello! Does shapeworks support shape model for 2D shape analysis (Contour based cases)? In the ‘Use cases’ it seems to be OK to analysis shape model for contour domains. But when i import 2D data, Errors jumped out suggesting that the data must be 3D. ---

Yes, ShapeWorks supports contour data, what file format are you using? @amorris ---

The types of contours we are currently supporting are as a series of points/lines in VTK files. Are you trying to use a 2D image segmentation? If so, we can investigate a way to convert it. ---

Yes，we tried to use 2D shape image segmentation，which was acquired from 3Dslicer. The file format is nrrd and the image is a 2D plane rather than some lines. Is there any tools to convert it？Thank you！ ---- Replied Message ---- > From | [Alan Morris via ShapeWorks](mailto:notifications@shapeworks.discoursemail.com)[notifications@shapeworks.discoursemail.com](mailto:notifications@shapeworks.discoursemail.com) | > > - | - | > Date | 09/08/2022 01:52 | > To | [xbyzju@126.com](mailto:xbyzju@126.com)[xbyzju@126.com](mailto:xbyzju@126.com) | > Cc | | > Subject | [ShapeWorks] About contour domains | > ![](https://global.discourse-cdn.com/free1/uploads/shapeworks/original/1X/cd5bd4b71fbe76e51aa3eb293d04a7cdd25acb62.png "amorris") | [amorris](https://shapeworks.discourse.group/u/amorris) > September 7 | > > - | - | The types of contours we are currently supporting are as a series of points/lines in VTK files.

I believe the vtkContourFilter can do this for 2D, but I don’t know that there is a ready-made tool to convert this at the moment. [https://kitware.github.io/vtk-examples/site/Cxx/Visualization/LabelContours/](https://kitware.github.io/vtk-examples/site/Cxx/Visualization/LabelContours/) ---

Thank you very much，I will try it. ---- Replied Message ---- > From | [Alan Morris via ShapeWorks](mailto:notifications@shapeworks.discoursemail.com)[notifications@shapeworks.discoursemail.com](mailto:notifications@shapeworks.discoursemail.com) | > > - | - | > Date | 09/09/2022 00:24 | > To | [xbyzju@126.com](mailto:xbyzju@126.com)[xbyzju@126.com](mailto:xbyzju@126.com) | > Cc | | > Subject | [ShapeWorks] About contour domains | > ![](https://global.discourse-cdn.com/free1/uploads/shapeworks/original/1X/cd5bd4b71fbe76e51aa3eb293d04a7cdd25acb62.png "amorris") | [amorris](https://shapeworks.discourse.group/u/amorris) > September 8 | > > - | - | I believe the vtkContourFilter can do this for 2D, but I don’t know that there is a ready-made tool to convert this at the moment.
