Musculoskeletal model of the hindlimb of Tyrannosaurus rex

This project consists of the SIMM model files for the MOR555 T. rex specimen (now at Smithsonian) used in the following paper:Hutchinson, J.R., Anderson, F.C., Blemker, S., Delp, S.L. 2005. Analysis of hindlimb muscle moment arms in Tyrannosaurus rex using a three-dimensional musculoskeletal computer model. Paleobiology 31:676-701. doi: 10.1666/04044.1It includes these files:1) A "bones" folder with .ASC format polygonal meshes at low resolution, as described in the above paper. Additional left leg files were generated as well as the third toe.2) .jnt and .msl files ("trex J42" and "trex M42") that are used by proprietary SIMM software (version 7.0) to run the model; these can be opened as text files in typical text applications.3) A snapshot of the SIMM model.Note that the SIMM model has undergone minor changes from the 2005 paper's model, but these are fairly trivial (except as noted above).More info: http://simtk-confluence.stanford.edu:8080/display/OpenSim/Tyrannosaurus+Rex+ModelAlso available at: https://figshare.com/articles/_/4982492OpenSim model has now been added (2019). <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=1284#pack_2149">SIMM model </a> : 2005-present SIMM model (.zip) </li> </ul>

本项目汇聚了用于MOR555 T. rex（现藏于史密森尼博物院）的SIMM模型文件，该模型文件应用于以下论文：Hutchinson, J.R., Anderson, F.C., Blemker, S., Delp, S.L. 2005. 基于三维骨骼肌肉计算机模型分析霸王龙后肢肌肉力矩臂的力学特性. 古生物学31:676-701. doi: 10.1666/04044.1。该套件包含以下文件：1) 包含低分辨率多边形网格的“.ASC”格式文件，其中“骨骼”文件夹如上所述；此外，还生成了左侧腿部文件以及第三趾的文件。2) “.jnt”和“.msl”文件（“trex J42”和“trex M42”），这些文件由专有SIMM软件（版本7.0）用于运行模型，它们可以作为文本文件在常规文本应用程序中打开。3) SIMM模型的快照。请注意，SIMM模型相较于2005年论文中的模型略有变动，但这些变动微乎其微（除非如上所述）。更多信息请参阅：http://simtk-confluence.stanford.edu:8080/display/OpenSim/Tyrannosaurus+Rex+Model。模型还可在以下链接获取：https://figshare.com/articles/_/4982492。OpenSim模型已添加（2019年）。此外，本项目还包括以下软件/数据包：
