   - See notebooks in the [Beetle Processing Repository](https://github.com/Imageomics/2018-NEON-beetles-processing) for more information and analyses of these values, addition and renaming of the above columns from the [original measurement CSV](https://huggingface.co/datasets/imageomics/2018-NEON-beetles/blob/bbefad05d50ed55da82e99bd330afe12a5fd1d97/BeetleMeasurements.csv), and the creation of the individual metadata CSV.
   - `BeetleMeasurements_resized.csv` has `pictureID`, `scientificName`, `genus`, `species`, `NEON_sampleID`, `siteID`, and `file_name` columns to display the resized images in the dataset viewer with some group image-level information. It will match up to information from `BeetleMeasurments.csv` on `pictureID`, though this is _not_ a unique alignment since it's not a unique ID for `BeetleMeasurements.csv`, but is for the resize.

 ### Data Splits
-This dataset does not have train-test splits.
+This dataset has a subset of the group images segmented to individuals and divided into an 80-20 train-test split in `Separate_segmented_train_test_splits_80_20/`.
