Introduction. Cellular identity is defined by a unique combination of expressed genes. … WebThis is the method that Scrublet uses to identify doublets - it assumes a bimodal distribution of doublet scores. 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).

"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. " - Doublet annotation generated by scrublet
