Selects the clusters that belong to a given percentile of the clusters with the largest physically interacting cells proportion based on FSC ratio thresholding. By default, the top 20 percent of clusters are chosen. Consider using ratio_cluster_plot to evaluate the choice of percentile cutoff.

Usage

select_dbt(
  obj,
  clusters = "seurat_clusters",
  ratio = "ratio_anno",
  ratio_high = "Ratio_high",
  assay = "FACS",
  quantile = 0.8,
  selected_clusters = "doublet_clusters"
)

Arguments

obj

The Seurat object.

clusters

The meta.data column containing the cluster labels (Default: seurat_clusters).

ratio

The meta.data column with the classification of cells into ratio_high and ratio_low using the FSC ratio (FSC.A/FSC.H) and a thresholding method.

ratio_high

The character string that indicates cells with a FSC ratio (FSC.A/FSC.H) above the threshold determined with calculateThreshold within the meta.data column.

assay

The Seurat assay containing FACS data.

quantile

The desired percentile cutoff above which clusters are classified as physically interacting cell clusters (Default 0.8, meaning top 20 percent of clusters are chosen).

selected_clusters

Character vector for the misc slot in the Seurat object that will contain the cluster numbers of the selected physically interacting cell clusters (Default: "doublet_clusters").

Value

Seurat object
