To view a set of sequencing runs for 10x Genomics Chromium Single Cell Gene Expression libraries run on both NextSeq™ 2000 P3 flow cells and NovaSeq™ 6000 SP v1.5 flow cells, please visit BaseSpace™ Sequence Hub. The 10x Genomics Chromium Single Cell Gene Expression assay is compatible with all Illumina ® platforms, but we recommend using NextSeq™ 550/1000/2000 and NovaSeq™ 6000 to be able to sequence multiple samples per run (see table 1 below).ġ0x Genomics Chromium Single Cell Gene Expression runs available on BSSH demo data page Single-cell sequencing data can also be analyzed using the Illumina DRAGEN™ Single-Cell app, available in the cloud on BaseSpace™ Sequence Hub, or locally on the NextSeq 1000 and NextSeq 2000 instruments. Sequencing for the single-cell gene expression library then happens on Illumina ® instruments, followed by analysis and data visualization using 10x Genomics Cell Ranger and Loupe Browser software. Today, we are excited to announce that we have published sequencing data for this product on BaseSpace™ Sequence Hub, including one set of libraries sequenced on the NextSeq™ 2000 P2 flow cell, and another set of libraries sequenced on a NovaSeq™ 6000 SP v1.5 flow cell.ġ0x Genomics Chromium Single Cell Gene Expression workflowĪ typical single cell RNA-Seq experiment with 10x Genomics Chromium Single Cell Gene Expression starts with a single cell or single nuclei suspension, followed by library preparation on the Chromium instrument (figure 1 below).įigure 1: The overall workflow for preparing 10x Genomics Single Cell Gene Expression libraries starts with a single cell or single nuclei suspension, followed by microfluidic single cell partitioning and barcoding with the Chromium instrument. The Chromium Single Cell Gene Expression assay provides single cell transcriptome 3' gene expression and multiomic capabilities. 10 x Genomics is a partner that develops multiple single cell and spatial biology solutions. Single-cell RNA-sequencing is a next-generation sequencing (NGS) method that examines the transcriptomes of individual cells, providing a high-resolution view of cell-to-cell variation.

The only significant difference that I see is in the Q30 Bases in Barcode which is low in the STAR solo run as compared to the Cell Ranger (~97.5%).Today, we’re sharing the fifth in a series of posts that shed more light on new run data publicly available on BaseSpace ™ Sequence Hub (BSSH). Which seems to be comparable to a CellRanger output summary for a sample that was mapped earlier. % of reads mapped to too many loci | 0.04% Number of reads mapped to too many loci | 30684 % of reads mapped to multiple loci | 4.33% Number of reads mapped to multiple loci | 3534767 Number of splices: Non-canonical | 280490 Number of splices: Annotated (sjdb) | 29052571 The final log out are as follows and indicate a good percentage of uniquely mapped reads. Thanks! I tried with putting the -soloBarcodeReadLength option in STAR to be 150 and there was no problem then.

In CellRanger the length of reads is R1 is not problematic as there are options to specify trimming or the tool just ignores the rest of the reads. Do I need to trim the R1 reads to a length of 28bp before alignment? or (b) Should I just specify the -soloBarcodeReadLength option in STAR to be 150? If UMI+CB length is not equal to the barcode read length, specify barcode read length with -soloBarcodeReadLength' 'SOLUTION: make sure that the barcode read is the last file in -readFilesIn, and check that it has the correct formatting

I have checked the FASTQ file for Read 1 and see that it is full 150bp. However, I am getting the following error and hope that some of you can help: EXITING because of FATAL ERROR in input read file: the total length of barcode sequence is 150 not equal to expected 28 I have some 10x v3 single cell rna seq fastq files that I am trying to map to human genome using STAR aligner.
