nf-core/marsseq
MARS-seq v2 pre-processing pipeline with velocity
1.0.0
). The latest
stable release is
1.0.3
.
Introduction
nf-core/marsseq is a bioinformatics pipeline for MARS-seq v2.0 preprocessing pipeline. As an additional work we have developed custom set of scripts to run velocity inference using StarSolo
.
We do so by converting the raw reads into 10X v2 format.
Usage
Note If you are new to Nextflow and nf-core, please refer to this page on how to set-up Nextflow. Make sure to test your setup with
-profile test
before running the workflow on actual data.
To run the pipeline you have create experiment metadata files:
and samplesheet (samplesheet.csv
). We provide test example here.
Next, you have to generate genome references to incorporate ERCC spike-ins. References are downloaded from GENCODE database.
Now, you can run the pipeline using:
Warning: Please provide pipeline parameters via the CLI or Nextflow
-params-file
option. Custom config files including those provided by the-c
Nextflow option can be used to provide any configuration except for parameters; see docs.
For more details, please refer to the usage documentation and the parameter documentation.
Pipeline output
To see the the results of a test run with a full size dataset refer to the results tab on the nf-core website pipeline page. For more details about the output files and reports, please refer to the output documentation.
