Human Sperm Flagellar Kinematics Across a Viscosity Range

46.4 MB of source data underlying a study on human sperm motility. The dataset provides quantitative measurements of flagellar kinematics across a physiological to high-viscosity range (1 to 36 mPa·s). It includes CNN-predicted 3D coordinates, calibration matrices, and Fourier mode profiles for sperm in distinct mechanochemical states, authored by Chao Li and last updated in April 2026.

Use Cases

• Modeling sperm flagellar dynamics based on 3D spatial coordinates and curvature amplitude.
• Comparing mechanochemical state-switching (Mode 1 vs. Mode 2) based on kinematic profiles.
• Calibrating and validating CNN-based motion tracking pipelines based on provided FWHM matrices and error distributions.
• Reproducing biophysical modeling and statistical analyses from the associated manuscript.

Strengths

• Data covers a physiological to high-viscosity range (1 to 36 mPa·s).
• Includes CNN-predicted 3D coordinates and detailed Fourier mode evolution profiles.
• Provided under a CC-BY-4.0 license for transparency and reproducibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided primarily in .mat format, requiring specific software (e.g., MATLAB) for access.
