The TENxXeniumData ExperimentHub package provides a collection of Xenium spatial transcriptomics datasets by 10X Genomics. These datasets have been formatted into the Bioconductor classes, the SpatialExperiment or SpatialFeatureExperiment (SFE), to facilitate seamless integration into various applications, including examples, demonstrations, and tutorials. The constructed data objects include gene expression profiles, per-transcript location data, centroid, segmentation boundaries (e.g., cell or nucleus boundaries), and image.
TENxXeniumData 1.3.0
Image-based spatial data, like Xenium, is typically focused on profiling a pre-selected set of genes. Such data can achieve resolution at the level of individual molecules, preserving both single-cell and subcellular details. Additionally, these methods often capture cellular boundaries through segmentations.
The TENxXeniumData package aims to provide a curated collection of Xenium
spatial transcriptomics datasets provided by 10X Genomics. These
datasets are formatted into Bioconductor classes, specifically the
SpatialExperiment or SpatialFeatureExperiment (SFE). Similar to SFEData,
TENxXeniumData is designed as an ExperimentHub package focusing on Spatial
Data, with a specific emphasis on Xenium.
A notable distinction lies in our constructed data object, where our primary focus is on Xenium data. We aim to capture detected molecules/transcripts crucial for gaining insights into subcellular details related to specific markers and the imaging data, in addition to the gene expression profile of each cell, the centroid, and the boundary of each cell. Additionally, we have chosen to employ SpatialExperiment as an alternative scheme for data representation. In this scheme, cellular segmentations are integrated into per-cell metadata of the constructed object,
To install the TENxXeniumData package from GitHub:
if (!require("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("TENxXeniumData")The TENxXeniumData package provides an R/Bioconductor resource for
Xenium spatially-resolved data by 10X Genomics.
The package currently includes the following datasets:
spe_mouse_brain (SpatialExperiment Bioconductor class)sfe_mouse_brain (SpatialFeatureExperiment Bioconductor class)spe_human_pancreas (SpatialExperiment Bioconductor class)sfe_human_pancreas (SpatialFeatureExperiment Bioconductor class)A list of currently available datasets can be obtained using the ExperimentHub interface:
