"CWL Tools & Workflows" is the community's best practices for CWL tool and workflow descriptions.
To submit a new workflow or tool description please make a pull request against this repository.
Any contribution submitted for inclusion in this repository shall be under the terms and conditions of the Apache License version 2.0 (see LICENSE.txt).
Please follow these recommendations before pull request:
- One file per tool or per logical part of the tool (those with subcommands)
- CWL tool description filename should have the same name as the tool (Tool’s name STAR CWL tool description filename
STAR.cwl
) if possible (no conflicts with existing files) and placed into tools directory - If a tool has subcommands, like samtools or bwa, use tool’s name dash subcommand name. For example,
bwa-mem.cwl
orsamtools-index.cwl
- Each CWL tool description should be provided with job and test files and placed into test directory
- Job’s filename has to be suffixed CWL file basename plus -job.json (bwa-mem-job.json, samtools-index-job.json)
- Test’s filename has to be suffixed CWL file basename plus -test.yaml (bwa-mem-test.yaml, samtools-index-test.yaml)
- Use docker for the tool your are describing
- If the tool has subcommands and you are going to use the same Docker image, move the DockerRequirement class into separate file (
samtools-docker.cwl
) and $import it - If you are a maintainer of the Docker image, it is good to provide content of Dockerfile in class DockerRequirement (dockerFile)
- If the tool has subcommands and you are going to use the same Docker image, move the DockerRequirement class into separate file (
Incomplete descriptions are welcome as long as they are usable. Generally sharing early & often is encouraged.
For your convinience Apache Jena Fuseki SPARQL server is provided. It automaticaly downloads new CWL tool descriptions converts them into XML/RDF format and makes available at https://sparql-test.commonwl.org. Each CWL tool becomes a graph that can be queried. Provided sample queries all the graphs where foaf:name "Dobin" is present.
PREFIX foaf: <http://xmlns.com/foaf/0.1/>
PREFIX doap: <http://usefulinc.com/ns/doap#>
SELECT distinct ?file ?name
WHERE {
graph ?file {
?P foaf:name ?name .
FILTER (regex(?name, "Dobin","i"))
}
}
LIMIT 25
Test directory includes:
- dm3_chr4.fa - Chromosome 4 of Drosophila genome
- dm3_chr4.gtf - Chromosome 4 RefSeq annotation file
- SRR1031972.fastq - The reduced raw reads file ( reads from Chromosome 4 only, RNA-Seq data)
To test tools run test/test.sh
from the repository root.
