Changes to parsim


All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[2.1.0] - 2020-08-03


  • Special parameters with parsim-related case information are available for macro expansion on case creation. They are also available as environent variables of the subprocesses started with the psm run command.

[2.0.0] - 2019-09-27


  • Implemented DOE scheme gsd (Generalized Subset Design), as available in pyDOE2 package. Allows reduced factorial designs with more than two levels.

  • With DOE scheme fracfact, the user can now define the reduced design either by a generator expression (option “gen”), or by the design resolution (option “res”).

  • Property-based getter functions in Case and Study classes now provide caselist, results and parameter info as pandas DataFrame or Series objects.

  • Study.collect() method now aggregates all collected results in a file “study.results” in the study directory. This file includes also cases with missing data (marked as “NaN”, pandas-style).

  • pyDOE2, numpy, scipy and pandas are now mandatory dependencies.

  • Constructor of Case class now handles colon-separated format <study>:<case> for cases inside studies. This simplifies use of the parsim Python API for working with results.

  • Examples of how to use the Python API for post-processing and data analysis.


  • Support for Python 2 has been removed!

  • Config option paramlist_upper_names has been removed (controlled optional automatic conversion of all parameter names to uppercase).


  • API changes in ParsimObjects (incl. subclasses Project, Study and Case), especially in constructors (__init__) and create() method. These changes makes the CLI command implementations shorter and easier to understand. Better checking of sane name and path arguments to constructor.

[1.0.0] - 2018-12-19



  • Now works with Python 3 (and Python 2.7, as before).

  • Fixed problems with parsing of DOE command-line arguments.

[0.7.0] - 2018-07-26
