simnibs-analyze

Post-processing and analysis pipeline for SimNIBS e-field outputs. Built to facilitate the analysis of simnibs simulations in the context of non-invasive brain stimulation studies (TMS/tDCS).

What it does

Starting from SimNIBS outputs, the pipeline covers the full analysis workflow:

• Target definition — generate ROI masks in MNI and subject space from MNI coordinates or atlas parcels (sphere, atlas-based)
• E-field preparation — coregister, skull-strip, smooth, and mask NIfTI volumes; intra/extra-ROI decomposition
• E-field analysis — extract scalar features (mean, max, percentiles, focality ratio) per subject and condition
• Single-subject optimisation assessment — evaluate how well a given montage targets the intended ROI
• Simulation robustness — assess sensitivity of the e-field distribution to input variability
• Stimulation method comparison — contrast montages or stimulation parameters across conditions
• Group-level analysis — inter-subject summary statistics, condition comparisons, and effect-size reporting
• Visualisation — 2D slice overlays, 3D surface rendering, histograms, and group bar plots

Installation

# TODO: publication sur PyPI
pip install simnibs-analyze

Prerequisite Data (Input structure from simnibs):

You need to have already run:

• simnibs-simulation or/ andsimnibs-optimization folder
• simnibs-m2m folder

Quick start:

• prepare a config file : use examples from (add link)
• then run: simnibs-analyze --config="pathToYourConfig.yaml"
