[[FFN paper]](https://www.nature.com/articles/s41592-018-0049-4), [[data from the paper]](https://storage.googleapis.com/j0126-nature-methods-data/GgwKmcKgrcoNxJccKuGIzRnQqfit9hnfK1ctZzNbnuU/README.txt)

We downloaded and processed the data into formats that are easier to share.
- Ground truth
  - train: `j0126-train-34vol.zip`, 34 densely labeled subvolumes   
  - validaiton: `valid_12_skeletons.h5`, manually traced skeletons for 12 neurons
  - test: `test_50_skeletons.h5`, manually traced skeletons for 50 neurons

- Image and FFN result
