Hello everyone,

I would like to be able to create 3 buttons in my Slicer Jupiter kernel. One that will act just like “save as” (download to the desktop .nrrd files), next an upload button doing exactly like this line does:  
**volume = slicer.util.loadVolume(‘Data/image.nrrd’)** but letting the user to choose his .nrrd file.  
And a screenshot button that will capture the scene displayed.

Thanks in advance

Hugo

You can use standard Jupyter widgets for file upload/download, as shown in “File upload/download” section in this example notebook: [https://github.com/Slicer/SlicerNotebooks/blob/master/01\_Data\_loading\_and\_display.ipynb](https://github.com/Slicer/SlicerNotebooks/blob/master/01_Data_loading_and_display.ipynb)

I’ve found that FileUpload widget is not reliable for large files ([https://github.com/jupyter-xeus/xeus-python/issues/272](https://github.com/jupyter-xeus/xeus-python/issues/272)), so you either need to upload using Upload button in the main notebook list or try the script posted [here](https://github.com/jupyter-xeus/xeus-python/issues/272) and if you find that it still does not work then add a note to that bug report.
