Simulated VisiumHD 8 µm binned SpatialExperiment dataset

A simulated SpatialExperiment object mimicking a 10x Genomics Visium spatial transcriptomics layout. The dataset contains spot-level spatial coordinates and cluster annotations, and is intended for testing.

Usage

data(visiumHD_simulated_spe)

Format

A SpatialExperiment object with:

assays

One dummy assay (required container structure)

colData

Spot metadata including barcode and cluster

spatialCoords

Numeric matrix of x/y spot coordinates

Source

Simulated internally for package development.

Details

This dataset contain only gene expression values for one gene named FAKE_GENE. The dummy assay is included solely to satisfy the SummarizedExperiment container requirements.

Spot coordinates follow a Visium-like squared grid. Cluster labels are simulated and have no biological meaning.

The layout is intended to mimic a Visium HD *binned* layer (e.g., 8 µm bin size), where each spot represents one bin arranged on an adjacent square grid.
