Pytheos provides a tool set for a wide range of tasks in high pressure science:

• calculate pressure from a number of built-in pressure scales
• convert pressure scales
• propagate uncertainties properly using the uncertainties package
• fit pressure-volume and pressure-volume-temperature data sets using the scipy and lmfit packages
• fit with a wide range of different equations and their combinations

Pytheos is a pure python package.

It can be installed from source or,

$ pip install pytheos

For anaconda users,

$ conda install -c shdshim pytheos

I provide environment files for mineral physicists. The environment file includes useful packages for mineral physicists. So those who are interested only pytheos may not want to use the environment files.

If you decide to use the environment, you may install the environment by:

$ conda env create -f py35ds-osx.yml

For window users, use: py35ds-win64.yml.

The command above will create a new environment: py35ds.

If you need more detailed one, please find my instruction in my gist site.

Please contact Dan Shim (shdshim@gmail.com) for bug reports, comments, and suggestions. I am happy to include new pressure scales or other pressure scales in pytheos as well.

The pytheos package includes examples in Jupyter Notebook (under the examples folder), which demonstrate a range of operations, calculations, and fittings you can do with pytheos. Pytheos is designed to support data analysis using Jupyter Notebook as well as python scripts.
