See here for an overview and explanations for this code.

The code for this example is in the test subdirectory of the ruffus module:

ruffus/test/intermediate_example.py

The data is at:

ruffus/test/data_for_intermediate_example

Programme options:

--help, -h

show help message

To specify tasks:

--target_tasks TARGET_TASK, -t TARGET_TASK

Target task(s) of pipeline. TARGET_TASK can be

• gwas_simulation
• statistical_summary

For example:

intermediate_example.py -t statistical_summary

--forced_tasks FORCED_TASK, -f FORCED_TASK

--jobs N, -j N

N specifies number of concurrent process running jobs in parallel

To specify paths:
