Speech sequencing in the human precentral gyrus

Code to recreate the figures from Liu*, Zhao*, Hullett, and Chang. "Speech
sequencing in the human precentral gyrus", Nature Human Behaviour, 2025.

Installing the Python environment

An environment with all relevant dependencies can be installed using Anaconda. In a terminal, use the following command:

conda env create -f environment.yml

Once created, the environment must be activated to properly run the figure code. Activate the environment with the following command:

conda activate sylseq

Environment creation was tested and verified on a MacBook Pro running Sonoma 14.6.1 and using Anaconda 24.5.0.

Downloading relevant data files

Datasets needed to generate the figures can be accessed and downloaded via Zenodo 10.5281/zenodo.15346719.

Once downloaded, place the files in a folder titled data within this repository. This repository should now have the following directory organization:

Liu2025_Sequencing
└───data
└───figures
└───imaging
└───sylseq_paper

Generating figures

Figures can be generated by running the figure notebooks in figures (e.g. through Jupyter). Notebooks are typically organized by processing data, defining functions for each figure panel, then assembling the overall figure. If there are supplementary figures associated with main text figures, those figures will be at the end of the notebook (and are noted in the filename of the notebook).
