Installation

Requirements

SCT requires a Python version equal or higher than 3.11.

To install SCT using pip:

Recommended installation

pip install sct[recommended]

This will install SCT together with the recommended set of analysis plugins (Point Target, Radiometric, Spectral, Interferometry, Elevation Notch, Ambiguity Ratio), graphing dependencies and web utilities.

If you only need the core framework without the optional dependencies:

Minimal installation

pip install sct

Virtual Environments

We recommend using a dedicated virtual environment to install the main SCT software.
This will ensure that the software is installed in a separate environment and avoids conflicts with other packages or dependencies.

Optional dependency groups

Extra	Description
`recommended`	All analysis plugins, graphs and web utilities
`analyses`	All analysis plugins
`graphs`	Matplotlib and graphical output support
`web`	Requests library for TEC map downloads
`localtesting`	Test with local input product readers
`test`	Testing framework (pytest, pytest-cov)
`dev`	Development tools (ruff, pylint)

Plugins installation

SCT is designed to be extensible and several plugins to support different input products formats have been developed and distributed as separate packages.

Refer to the official plugins documentation for further information on how to install plugins.
