I've recently started working with the 10X-Genomics platform with Illumina (MiSeq and HiSeq) for single-cell RNA-Seq The easiest way to use SingleR is to annotate cells against built-in references. We did not apply score-based cell type assignment and fold-change filtering, because of high expression of a few rod genes. Genewise read counts for cells with at least 500 reads were exported to Matrix Market format files and read into R with edgeR's read10X function. In the config file, the directory of cellranger references is named as cellranger . by comparing the alignments produced by Cell Ranger and bowtie2 on the transcriptome reference. When analyzing 3' Gene Expression data, Cell Ranger 4.0 trims the template switch oligo (TSO) sequence from the 5' end of Read-2 and the poly-A sequence from the 3' end before aligning reads to the reference transcriptome. If we want to build pre-mRNA references, in which we use full length transcripts as exons in the annotation file. There are several versions of Cell Ranger reference that come pre-packaged with the software; 2020-A is the newest version of reference to date.
