C3D Extraction Toolbox

This toolbox is of benefit to musculoskeletal modellers in the field of biomechanics / bioengineering to assist extracting kinematic, kinetic, and EMG information directly from a C3D file for Matlab manipulation or for input to OpenSim biosimulation software. The scripts can be configured for any laboratory configuration. This software is free without warranty but I do ask for acknowledgement if used in publications. Free download is available with documentation and two examples included. Main features of this script include:Custom markerset extractionFoot-plate detection algorithmKinetic extraction (ground reaction forces / moments)Center of pressure calculationTransformation to customizable model coordinate systemCustom EMG acquisition & processing toolsXML file production (for OpenSim)Lab customizableThe scripts require Motion Labs C3D Server software (freeware) and XML Toolbox (Marc Molinari)(freeware) which is included with the script download. Also requires Matlab 2008 or greater (32 bit only) with the Signal Processing Toolbox.Additional C3D software may be useful and these are available at http://www.c3d.org/c3dapps.html. Review the included manual for version updates and additions. Please inform me of bugs / suggestions to improve as this will be an ongoing project. <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=341#pack_574">GaitExtractToolbox </a> : Gait Extract Toolbox for Matlab </li> </ul>

此工具箱专为生物力学与生物工程领域的骨骼肌肉建模者设计，旨在协助从C3D文件中直接提取运动学、动力学和肌电图（EMG）信息，以便于Matlab操作或作为OpenSim生物模拟软件的输入。脚本可根据任何实验室配置进行调整。该软件免费提供，但若在出版物中使用，恳请予以认可。下载包含文档和两个示例的免费版本。脚本的主要功能包括：定制标记集提取、足底检测算法、动力学提取（地面反作用力/力矩）、压力中心计算、转换为可定制模型坐标系、定制EMG采集与处理工具、生成XML文件（用于OpenSim）、实验室定制化。脚本运行需要Motion Labs C3D服务器软件（免费软件）和XML工具箱（Marc Molinari）（免费软件），这两者均包含在脚本下载中。此外，还需要Matlab 2008或更高版本（仅32位）以及信号处理工具箱。额外的C3D软件可能也很有用，这些软件可在http://www.c3d.org/c3dapps.html获取。请查阅包含的说明书以了解版本更新和新增功能。如发现错误或改进建议，请告知，因为这将是一个持续进行的项目。本工程包括以下软件/数据包：
