AlertValueDetail
High Fraction of Reads Mapped Antisense to Genes22.9%Ideal < 20%. Rates of up to 40% are common for single nuclei samples. Higher fraction of antisense reads may indicate use of an incorrect chemistry type, or an issue with the reference transcriptome.
Low Fraction Reads in Cells55.7%Ideal > 70%. Application performance may be affected. Many of the reads were not assigned to cell-associated barcodes. This could be caused by high levels of ambient RNA or by a significant population of cells with a low RNA content, which the algorithm did not call as cells. The latter case can be addressed by inspecting the data to determine the appropriate cell count and using --force-cells.
Intron mode usedThis data has been analyzed with intronic reads included in the count matrix. This behavior is different from previous Cell Ranger versions. If you would not like to count intronic reads, please rerun with the "include-introns" option set to "false". Please contact support@10xgenomics.com for any further questions.
