CORAL Samples

This directory contains a small set of randomly selected sample files from the large-scale CORAL dataset, a whole-brain neuron tracing benchmark. These samples are provided as lightweight examples for quick inspection, visualization, and testing of different CORAL data types without downloading the full dataset.

Data Description

cubes-5/
- Contains 5 examples for CORAL block-level tasks.
- Each example includes a 3D cube image block in .tif format.
- Files with the same basename and the .swc extension are the corresponding neuron structure annotations.
- Files with the same basename and the _mask.tif suffix are the corresponding mask annotations.
slices-5/
- Contains 5 randomly selected 2D slices from whole-brain image data in .tif format.
neuron-swcs-3/
- Contains 3 complete neuron annotations in .swc format.
- These files provide examples of full-neuron morphology labels from CORAL.
