cellranger process single-end scRNAseq #179

Closed BenxiaHu closed 2 years ago

BenxiaHu commented 2 years ago

Hello, I am just wondering whether cellranger count can process single-end scRNA-seq. This paper said that they used cellranger to process single-end scRNA-seq(https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE129519). The Cell Ranger 2.0.1 pipeline (10X Genomics) was used to align reads from RNA-seq to the GRCh38 human reference genome and produce the associated cell by gene count matrix.

Thanks in advance.

Cell Ranger does not process single end data, and that paper seems to have used paired end data

Single-cell RNA-Seq libraries were prepared with the Chromium™ Single Cell 3’ Library & Gel Bead Kit v2 (10x Genomics, PN-120237). Libraries from different samples were pooled based on molar concentrations and sequenced on a NextSeq 500 instrument (Illumina) with 26 bases for read 1, 57 bases for read 2 and 8 bases for Index 1

Which likely explains how they still managed to use Cell Ranger.
