Import of this file worked for me:

You need to wait several minutes, because the module does block updates while placing points one by one. I’ve submitted a [pull request](https://github.com/stephan1312/SlicerEAMapReader/pull/7) that makes the import faster (still a few ten seconds).

Did you acquire the files yourself? Can you describe the steps of how you exported the data from Carto?

There is lots of room for improvements in the module. It should be possible to speed up the import, store all the values as measurements, maybe add an option to load the points as colored glyphs (can be generated from the fiducials), and of course it could be made a proper extension that can be installed from the Extensions manager by a few clicks.

@stephan are you still around? Would you be interested in making some improvements and submitting the extension to the Extensions index so that EA Map Reader shows up in the Extensions manager?
