+Then, each dataset will have its own base directory with the name being the dataset identifier. Inside each dataset directory we will find 3 subdirectories:
 
 - `3d`: containing the 3D models for the neurons with the file name following `<neuron name>.stl`, with the exception of `nervering.stl`.
-- `em`: storing each slice tileset in its own subdirectory and a `metadata.json` file with information required to represent the tiles in the frontend application _(TODO: define `metadata.json` format)_.
-- `segmentations`: stores all the segmentation json files following the namming schema `s<slice>.json`, where `slice` is a positive integer (can contain left padding zeros).

+- `segmentations`: stores all the segmentation json files following the namming schema `s<slice>.json`, where `slice` is a positive integer (can contain left padding zeros). It also contains a metadata file (for an example see: [./tests/fixtures/segmentation/metadata.json](./tests/fixtures/segmentation/metadata.json))
