Number of Reads
Total number of single-end reads that were sequenced.
Valid Barcodes
Fraction of reads with barcodes that match the whitelist.
Reads Mapped Confidently to Transcriptome
Fraction of reads that mapped to a unique gene in the transcriptome with a high mapping quality score as reported by the aligner.
Reads Mapped Confidently to Intergenic Regions
Fraction of reads that mapped to the intergenic regions of the genome with a high mapping quality score as reported by the aligner.
Reads Mapped Confidently to Intronic Regions
Fraction of reads that mapped to the intronic regions of the genome with a high mapping quality score as reported by the aligner.
cDNA PCR Duplication
The fraction of duplicated reads that can be attributed to the cDNA amplification process; this is the number of non-unique reads divided by the number of reads.
Q30 Bases in Barcode
Fraction of bases with Q-score at least 30 in the cell barcode sequences.
Q30 Bases in Read 1
Fraction of bases with Q-score at least 30 in the read 1 sequences.
Q30 Bases in Sample Index
Fraction of bases with Q-score at least 30 in the sample index sequences.
Q30 Bases in UMI
Fraction of bases with Q-score at least 30 in the UMI sequences.
