spaceranger

Description

Count gene expression and protein expression reads from a single capture area.

Inputs

Name	Type & Properties	Description
--gex_reference	file required	Path of folder containing 10x-compatible reference
--input	file required multiple	The fastq.gz files to align. Can also be a single directory containing fastq.gz files. Individual FASTQ files should follow the naming convention of 10x Genomics: [Sample Name]_S[Sample Number]_L[Lane Number]_[Read Type]_001.fastq.gz Where: [Sample Name] is the name assigned during sample preparation/sequencing S[Sample Number] is the sample index (usually S1, S2, etc.) L[Lane Number] identifies the sequencing lane (L001, L002, etc.) [Read Type] will be one of: R1 - Read 1 (contains the spatial barcode and UMI) R2 - Read 2 (contains the actual cDNA sequence)
--probe_set	file required	CSV file specifying the probe set used
--cytaimage	file	Brightfield image generated by the CytAssist instrument. When using CytAssist workflow, either this or --image must be provided.
--image	file	H&E or fluorescence microscope image in TIFF or JPG format. Required for standard Visium workflow, optional when using --cytaimage for CytAssist workflow.
