SingleR is an automatic annotation method for single-cell RNA sequencing data that uses a given reference dataset of samples (single-cell or bulk) with known labels to label new cells from a test dataset based on similarity to the reference. Two mouse reference datasets (MouseRNAseqData and ImmGenData) and two human reference datasets (HumanPrimaryCellAtlasData and BlueprintEncodeData) from CellDex R package [2] are currently available.
This function will merge an external table of cell annotations into an existing Seurat Object's metadata table. The input external metadata table must have a column named "Barcode" that contains barcodes matching those found in the metadata already present in the input Seurat Object. The output will be a new Seurat Object with metadata that now includes the additional columns from the external table.

Furthermore, the tool allows for the application of filters to the data, setting thresholds, and providing annotations to notify users if cells meet the established thresholds. The visualization can be improved by omitting extreme values. The tool also facilitates the creation of a heatmap to represent the density distribution of cells and exhibit the raw gene/protein expression values.

It also generates a dot plot using Seurat's Dotplot function [3], providing a visual representation of the percentage of various cell types within each cluster. Typically, a cluster can be more distinctively named by the predominant cell type as seen in the dotplot. The plot's order can be customized for the clusters and cell types. If no specific order is provided, the function uses a default order.

This functions combines multiple sample level Seurat Objects into a single Seurat Object and normalizes the combined dataset.
