If True/set, post processing scripts are enabled in the given `project`. Only set this if you are sure that you can trust the given project file because it may be a security vulnerability. seaborn_style: str The name of the style of the seaborn package that can be used for the :func:`seaborn.set_style` function output_project: str The name of a project file to save the project to concat_dim: str The concatenation dimension if multiple files in `fnames` are provided chname: dict A mapping from variable names in the project to variable names in the datasets that should be used instead """
