pyslice 1.7

Pyslice is a templating engine to easily create data sets for parametric modeling.

Welcome to Pyslice - dataset template engine's documentation!

Pyslice is a specialized templating system that replaces variables in a template data set with numbers taken from all combinations of a grouped series of numbers. It creates a dataset from input template files for each combination of variables in the series.

The main function of Pyslice is to provide utility functions for parametric modeling. Parametric modeling is a process of varying many inputs to a model. A drawback to parametric modeling is that there are usually hundreds to thousands of data sets to prepare and a corresponding number of model runs. Pyslice will create the model data sets and manage the model runs, or place the model runs in a queue managed by other software. Pyslice is also useful in establishing the sensitivity of a model to changing parameters.

Changes

2005-08-30: v1.6 Moved to threads rather than 'os.fork/os.exec' which means that pyslice.py should be able to run on Windows, though not tested. Eliminated a bunch of code required by the 'os.fork/os.exec' that should make pyslice.py easier to maintain.

2005-06-06: v1.5 Uses 'pyslice.ini' instead of 'pyslice.conf'. This allows the use of .ini editors to easily map to the correct format.

2005-05-30: v1.4 Can pull variable values from statistical distributions in Python's 'random' package. Uses os.path.walk to make considerable faster. Minor code clean-up

2004-12-16: v1.3 Now depends on Python 2.x or better. Am now using the PySPG library (http://pyspg.sourceforge.net/) in order to develop the variable sets. Because of PySPG now have the capability of doing geometric and list based parameter generation.

2001-07-10: v1.1 Removed Python 2.x dependencies. Variables can now use floating point. Works correctly to just create data sets by setting max_processes = 0 in pyslice.conf. Changes to documentation.

2001-07-10: v1.0 Initial release
