The settings config enables a user to alter the settings for almost all settings available in the tools used for a given pipeline.
This config file should be written in either JSON or YAML format. It can contain setup settings like:

### 4 levels of configuring settings
In biopet, a value of a ConfigNamespace (e.g., "reference_fasta") for a tool or a pipeline can be defined in 4 different levels.
* Level-4: As a fixed value hardcoded in biopet source code
* Level-3: As a user specified value in the user config file
* Level-2: As a system specified value in the global config files. On the LUMC's SHARK cluster, these global config files are located at /usr/local/sasc/config.
* Level-1: As a default value provided in biopet source code.
During execution, biopet framework will resolve the value for each ConfigNamespace following the order from level-4 to level-1. Hence, a value defined in the a higher level will overwrite a value define in a lower level for the same ConfigNamespace.
| -o | --outputConfig | Path (**required**) | Name of the config file that gets generated.|
| -s | --outputScript | Path (optional) | Biopet can also output a script that can be directly used for running the pipeline, the call of the pipeline is generated with the config file as input. This parameter sets the name for the script file.|
| -t | --template | Path (optional) | A template file with 2 placeholders *%s* is required for generating the script. The first placeholder will be replaced with the name of the pipeline, the second with the paths to the sample and settings config files. When Biopet has been pre-configured to use the default template file, then setting this parameter is optional. |

[Gears](gears.md) is run automatically for the data analysed with `Shiva`. There are two levels on which this can be done and this should be specified in the [config](../general/config) file:
*`mapping_to_gears: unmapped` : Unmapped reads after alignment. (default)
*`mapping_to_gears: all` : Trimmed and clipped reads from [Flexiprep](flexiprep).
*`mapping_to_gears: none` : Disable this functionality.
