Mathematical models in biology have many parameters, and sampling parameter values is necessary, for instance to identify robustness or sensitivities in the model, or simply calculate a phase diagram. We provide a universal program: Preconfig, that can be used within different computing pipelines to sample parameters. From a template file, Preconfig will generate multiple configuration files, covering all the combinations of parameter values specified as inclusions in the template. Fixed ranges or random sampling can be combined, and non-linear or interdependent variations are easily specified. Preconfig is open source and available on GitHub at
