Reading dicom files won't work
See https://gitlab.kitware.com/iMSTK/iMSTK/-/blob/master/Source/MeshIO/imstkMeshIO.cpp#L63
the first few lines say
bool isDir = false;
if (isDir)
{
// Assume that the directory is a collection of DICOM files
return VTKMeshIO::read(filePath, MeshFileType::DCM);
}
Dicom files will never be read this way
