Cell Ranger is a set of analysis pipelines, from 10X Genomics, that process Chromium single cell data to align reads, generate feature-barcode matrices, perform clustering and other secondary analysis.
The following Cell Ranger tools are available on Galaxy Australia:
cellranger mkfastq
demultiplexes raw base call (BCL) files generated by Illumina sequencers into FASTQ files. It is a wrapper around Illumina's bcl2fastq, with additional features that are specific to 10x Genomics libraries and a simplified sample sheet format.
cellranger count
takes FASTQ files from cellranger mkfastq
and performs alignment, filtering, barcode counting, and UMI counting. It uses the Chromium cellular barcodes to generate feature-barcode matrices, determine clusters, and perform gene expression analysis. The count pipeline can take input from multiple sequencing runs on the same GEM well. cellranger count
also processes Feature Barcode data alongside Gene Expression reads.
cellranger mkgft
is a simple utility to filter genes based on their key-value pairs in the GTF attribute column.
Cell Ranger is available on Galaxy Australia for Australian researchers. Please apply for access, using your institutional email.
