comet-toolbox 0.9

Dynamic functional connectivity toolbox for multiverse analysis

Comet - A toolbox for dynamic functional connectivity and multiverse analysis

About the toolbox

Please refer to the documentation for detailed information about the toolbox. The following README will only provide a very brief overview.

Please also note that the package is in an early stage of development, with frequent changes being made. If you intend to use this package at this stage, please feel free to contact me via the email address in the pyproject.toml file. Some features are also not yet tested, so there will be bugs (the question is just how many).

Installation and usage

It is recommended to use a dedicated Python environment (e.g. through conda) to mitigate the risk of potential version conflicts. Installation is possible through the Python Package Index (PyPI) or from the source code in this repository:

pip install comet-toolbox

Usage of the toolbox is then possible through either the GUI:

comet-gui

or (for more versatile usage) through the scripting API. For this, demo scripts are provided as starting points:

• Demo script for calculating dFC
• Demo script for performing multiverse analysis
• Demo script for multiverse analysis example from the preprint (+ additional visualizations)
• Demo script for graph analysis
