Indrops config 2

An example for running the OneCellPipe pipeline of OneCellBio with a pre-defined configuration file for sequencing runs with a single part, and a single library.
Files:

• R1.fastq.gz
• R2.fastq.gz

Command line:

nextflow onecellpipe.nf  --config /data/onecellpipe/data_results/indrop_config_to_use.yaml --out /data/onecellpipe/data_results

indrop_config_to_use.yaml:

# project and library settings

    version : "v2"
    dir : "/data/onecellpipe/data"
    fastq_path : "{read}.fastq.gz"

    d : 600 #Maximal distance from transcript end, NOT INCLUDING THE POLYA TAIL
