[[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

- FFN result (due to the file size constraint, we split the zip into two files)
```
# first, merge the two parts together
zip -s 0 ffn_seg_part.zip --out ffn_seg.zip
rm ffn_seg_part*
# then, unzip the segmentation in tiles of the size 128x2048x2048 (saved in h5)
unzip ffn_seg.zip
```
