Below, we propose a computational approach, Scrublet (Single-Cell Remover of Doublets), for identifying multiplets and apply the method to several datasets that include some measure of ground truth labels for cell multiplets. Briefly, our method involves two steps.

WebApr 24, 2024 · This strategy assumes (1) that a cell type’s frequency in the final dataset reflects that cell type’s contribution to the doublet pool, and (2) that user-defined cell-type groups approximate the magnitude of transcriptional divergence necessary to make a detectable heterotypic doublet.

WebJul 22, 2024 · If a cell contains barcodes from A and B, its doublet annotation would be lost for that simulation. We drew random pairs 100 times and ran Solo to supplement the remaining apparent experimental doublet annotations that still cross merged hash barcode groups. We measured how well Solo recovered the lost doublets using average precision.

Those droplets with lower scores should be singlets and those with higher scores should be doublets. It identifies the correct threshold by identifying the minimum of the bimodal distribution of simulated doublets (right). uk citizen driving in italy
