Conversation with Steve Pieper:

Ah - interesting - I think you found a windows-specific bug in the data bundle. Since the DICOM module prefixes the loaded volumes with the series number followed by a colon, the name of the volume node isn't always a valid windows path - in this case it is mistaken for a drive letter but that only happens for certain dicom series names.

I'll have to look into this and see if there's good generic fix for this. If you have a chance, could you file a bug report on this and send me the link? I've got to run now but should be able to clean it up pretty quick once I have a minute.

Hi Steve,

Thanks again for fielding the call today and pointing me to the MRB
file. I was testing out the highlighted lines you showed me but it
still looks as if I’m encountering the 0KB .nrrd file issue when I
call SlicerSaveSceneToDataBundleDirectory(). The weird part is it
loads fine, though the MRB does not.

Could this be because of how I how loaded the dicoms into the
slicer.dicomDatabase? (Below.)

i = ctk.ctkDICOMIndexer()

    for root, dirs, files in os.walk(cachedPath):

            for relFileName in files:

                dicomFilePath = os.path.join(root, relFileName)

                i.addFile(slicer.dicomDatabase, dicomFilePath,

cachedPath)

                slicer.app.processEvents()

I’ve attached a zip of the SaveSceneToSlicerDataBundleDirectory result
and the mrb. In the zip, you’ll find that the .nrrd file in “./Data/”
has a file size of 0. Nevertheless, it loads when I drop it into
slicer. The MRB, however, does not.

Here are my lines of python code – nothing fancy:

(First load the DICOM set into Slicer via the DICOM module.
Everything looks OK.)

applicationLogic = slicer.app.applicationLogic()

sceneSaveDirectory = 'C:/Users/skumar01/Desktop/xnatslicerbeta/saveTest'

mrbFilePath= 'C:/Users/skumar01/Desktop/xnatslicerbeta/MRBtest.mrb'

applicationLogic.SaveSceneToSlicerDataBundleDirectory(sceneSaveDire
ctory,
None)

True

applicationLogic.Zip(mrbFilePath,sceneSaveDirectory)

True

Any help you have is appreciated. Thanks again.
