Growth Rate Index Calculater wrapped by CWL

• cwl-runner such as cwltool
• Docker
  • If you cannot use docker, this tool runs with --no-container options.
  • However, you have to install dependent tools of RaGOO, such as R, samtools, and so on
• Database file (for multiplex mode)
  • See document of GRiD

With the CWL reference implementation (cwltool), toil-cwl-runner, or arvados-cwl-runner as your cwl-runner:

cwl-runner --outdir ${PATH_TO_OUTPUT_DIR} \
           tools/grid_single.cwl \
           -r ${PATH_TO_FASTQ_DIR} \
           -g ${PATH_TO_FASTA_FILE} \
           -o ${OUTPUT_DIR_NAME}

For other runners an input object is required:

inputs.yml

r:
  class: Directory
  path: path/to/fastq/dir
g:
  class: File
  path: path/to/fasta/file
o: output_name

cwl-runner --outdir ${PATH_TO_OUTPUT_DIR} \
           workflows/grid_single.cwl \
           inputs.yml

By default, GRiD generates an alignment file with bowtie2. If the input FASTQ file size is large, the size of this intermediate sam file will also increase. In the standard setting of cwltool, this intermediate file is output to a directory temporarily created on /tmp, and as a result, there is a possibility that the capacity of the system disk will be exhausted. To avoid this, we recommend changing the temporary directory using --tmpdir-prefix and --tmp-outdir-prefix.
