Filename for a YAML file that specifies Gaussian process options


.. toctree::
   :hidden:
   :maxdepth: 1



**Specification**

- *Alias:* None

- *Arguments:* STRING

- *Default:* no advanced options file


**Description**


The YAML file contains configuration options
that are used to populate a Teuchos ParameterList used by the Gaussian process
that will override other keyword-specified parameters.
Missing options in the YAML file are set to default values.
