Operating system:Windows 11  
Slicer version:3D slicer 5.2.2  
Expected behavior:I want to export the seg.nrrd file together with the original nrrd file as a dicom file

Please try with latest Slicer Preview Release and [follow these instructions](https://slicer.readthedocs.io/en/latest/user_guide/modules/segmentations.html#dicom-export). If you get stuck then let us know.

When I download the relevant extension, I try to export the seg.nrrd and .nrrd files as dicom, but I am prompted that the seg.nrrd file cannot find the referenced volume, how can I fix this?
