LARRY: Processed Single-Cell RNA Velocity Data for FlowMap Tutorial

A 1.3 GB serialized FlowMap tutorial object derived from the LARRY clonal hematopoiesis single-cell RNA velocity dataset. It contains fitted embedder coordinates, embedding-space velocities, gene-level expression and velocity matrices, and minimal cell metadata. The data were processed by jingyuan hu and last updated on May 13, 2026.

Use Cases

• Reproduce FlowMap trajectory tutorials based on the provided two-dimensional FlowMap coordinates.
• Demonstrate gene-gradient analysis using the included gene-level expression and velocity matrices.
• Learn curvature analysis methods with the supplied embedding-space velocities.
• Study hematopoiesis lineage tracing concepts using the processed LARRY dataset.

Strengths

• File size is 1.3 GB, indicating substantial processed data.
• Includes multiple data components like coordinates, velocities, and expression matrices for tutorial reproduction.
• Derived from a well-cited original study (Weinreb et al., Science, 2020).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided only as a processed tutorial object, not as raw biological measurements.
