| Description |
UMI Matrix
|
| Data processing |
Multiplexed libraries were sequenced with paired-end sequencing. The first read of each read pair contained exclusively barcoding information: a 6 nt sample barcode and a 10 bp unique molecular identifier (UMI). Paired-end reads were demultiplexed based on the sample barcodes, requiring a perfect match to one of the barcode sequences. The UMIs were extracted and appended to the read 2 sequence identifiers. The submitted fastq files are demultiplexed files for read2, with the UMI from read 1 appended to the sequence identifiers.
Prior to alignment, reads were trimmed and filtered using Fastp with parameters -y -x -3 -f 6. Reads were then aligned to the AGPv4 genome assembly using HiSat2.
The number of UMIs for each gene and each sample were counted, allowing for a 1 bp mismatch in UMIs to avoid over-counting artifacts resulting from sequencing errors
Assembly: AgpV4
Supplementary files format and content: CSV containing the UMI counts for each cell (column) and gene (row)
