IDStools - IMAS IDS Python Tools

A comprehensive Python toolset for working with IMAS (Integrated Modelling and Analysis Suite) Interface Data Structures (IDS) in fusion research.

Overview

IDStools provides a collection of command-line utilities and Python libraries for:

• Database Operations: List, copy, compare, and manipulate IDS data entries
• Data Analysis: Extract, validate, and analyze fusion plasma data
• Visualization: Plot equilibrium, profiles, and other physics quantities
• Format Conversion: Convert GEQDSK files to IDS equilibrium format

Key Features

Database Tools

• idslist - List available IDSs and their time slices
• idscp - Copy IDSs between data entries
• idsdiff - Compare IDSs and highlight differences
• idsperf - Profile IDS access performance
• dblist - List database entries and pulses

Analysis Tools

• eqdsk2ids - Convert GEQDSK equilibrium files to IDS format
• idsprint - Print IDS data values and structures
• idsresample - Resample IDS data in time
• plotequilibrium - Plot equilibrium data
• plotkineticprofiles - Visualize kinetic profiles

Data Validation

• Built-in COCOS (Coordinate Conventions) validation
• IDS structure and physics consistency checks
• Data quality assessment tools

Installation

From PyPI

pip install imas-idstools

From Source

git clone https://github.com/iter-organization/IDStools.git
cd IDStools
pip install .

Quick Start

List IDSs in a pulse

idslist --uri "imas:mdsplus?user=public;pulse=134174;run=117;database=ITER;version=3"

Plot equilibrium

plotequilibrium --uri "imas:mdsplus?user=public;pulse=134174;run=117;database=ITER;version=3"

Requirements

• Python ≥ 3.8
• IMAS Python Access Layer (imas-python)
• NumPy, Matplotlib, Pandas
• Rich (for enhanced terminal output)
