Zebrafish Genotype Image Dataset

Zebrafish Genotype Image Dataset (.npz format)

This dataset contains color brightfield microscopy images of zebrafish used in the study:

“Genotype-Phenotype Relationships in Zebrafish Hypophosphatasia: An AI-Based Approach”.

File Contents

The .npz archive contains:

• images: NumPy array of shape (N, H, W, C) – RGB images

• labels: Integer labels (0 = wildtype, 1 = heterozygous, 2 = homozygous)

• filenames: Original PNG filenames (for traceability)

Usage

To load the data in Python:

import numpy as np

data = np.load("zebrafish_dataset.npz", allow_pickle=True)

images = data["images"]
labels = data["labels"]
filenames = data["filenames"]
