Data and code for multi-engine Monte Carlo evaluation of permanent iodine-125 implant dosimetry
Description
This dataset supports a multi-engine computational investigation of permanent iodine-125 implant dosimetry using TOPAS, OpenGATE, and PENELOPE. It includes frozen dose data, simulation contracts, input configurations, run matrices, analysis code, structure masks, convergence analyses, processed dose distributions, dosimetric metrics, figure data, and provenance records. TG-43 is documented only as an analytical planning baseline and is not included as an equivalent Monte Carlo engine or in absolute cross-engine comparisons.

Steps to reproduce
The dataset supports reproducible analysis of a multi-engine Monte Carlo study of permanent iodine-125 implant dosimetry. Simulation configurations are provided for TOPAS, OpenGATE, PENELOPE, and the analytical TG-43 implementation. Reproduction requires the software versions and computational environments listed in SOFTWARE_VERSIONS.md. The workflow is organized as follows: Review the geometry, source, physics, grid, and normalization contracts. Use RUN_MATRIX.csv to identify each experiment, engine, random seed, source count, and number of histories. Generate engine-specific inputs using the supplied configuration and runner scripts. Execute the Monte Carlo simulations with the documented software versions. Apply the frozen common structure masks to the resulting dose distributions. Run the supplied analysis scripts to calculate convergence, uncertainty, dose-per-primary, relative dose-volume metrics, and inter-engine comparisons. Regenerate tables and figures using the source-data files and analysis scripts included in the dataset. Raw Monte Carlo outputs that cannot be included because of repository size constraints are traceable through SHA-256 hashes, experiment manifests, and provenance records. Exact commands and software requirements will be provided in REPRODUCTION_WORKFLOW.md in the final dataset version.
