Running


To create BioWardrobe's dags run biowardrobe-init in airflow's dags directory
cd ~/airflow/dags
./biowardrobe-init



Run Airflow scheduler:
airflow scheduler



Use airflow trigger_dag with input parameter --conf "JSON" where JSON is either job definition or biowardrobe_uid
and explicitly specified cwl descriptor dag_id.
airflow trigger_dag --conf "{\"job\":$(cat ./hg19.job)}" "bowtie-index"

where hg19.job is:
{
"fasta_input_file": {
"class": "File",
"location": "file:///wardrobe/indices/bowtie/hg19/chrM.fa",
"format":"http://edamontology.org/format_1929",
"size": 16909,
"basename": "chrM.fa",
"nameroot": "chrM",
"nameext": ".fa"
},
"output_folder": "/wardrobe/indices/bowtie/hg19/",
"threads": 6,
"genome": "hg19"
}



All the output will be moved from temporary directory into output_folder parameter
of the job.
