StarScope

StarScope

StarScope provides a convenient way to run ThunderBio single cell analysis nextflow pipelines. scRNA-seq workflow uses starsolo (https://github.com/alexdobin/STAR/blob/master/docs/STARsolo.md) and Seurat package (https://satijalab.org/seurat/) as the core modules to process 3’ single cell RNA-seq data and generate a concise HTML report. We also integrated single cell immune repertopire and ATAC analysis workflows as other two subcommands, both of which were also built using nextflow.

Quick Start with ThunderBio Example Data

ThunderBio will provide human and mouse pre-built reference and two sets example data upon request. The demo_data fold contains two directories, human and mouse. In each directory, user could invoke the pipeline by running command below. Please note the reference index has to be placed in the same parent folder of the demo_data.

## Human Data Testing with conda or docker
cd demo_data/human
starscope run --input sampleList.csv --config thunderbio_human_conda.config
starscope run --input sampleList.csv --config thunderbio_human_docker.config
## Mouse Data Testing with conda or docekr
cd demo_data/mouse
