proceduraldata 2.0.4

Simple-to-understand and robust data storage for experimental data

This procedural data storage package provides a self-contained interface focused exclusively on storing and reading experimental data, using an approach independent of the specific measurement framework used for instrument control.

The main goals are to provide an interface that:

• Automatically stores a lot of metadata, including parameters that change during a measurement.

• Is procedural rather than functional in terms of the API the experimenter sees, as procedural programming tends to be easier to understand for a typical experimental physicist.

• Uses standard Python flow-control constructs (for, while, if, etc.) for looping over setpoints.

• The API aims to be self-explanatory, wherever possible.

In practice, the experimenter calls an explicit add_points(<new data points>) function to add rows to a traditional table of data points, with user-defined columns. In the background, pdata automatically records all changes to instrument parameters each time add_points is called.

In addition, pdata provides useful helpers for reading back the data, including automatically recorded instrument parameters, basic helpers for visualization, and good export capabilities to other tools for further analysis.
