Project description

msk_modelling_python (pre-release)

A Python package for musculoskeletal modelling.

Author: Basilio Goncalves, PhD, University of Vienna, 2024


Pre-requisites for Installation

  1. Download a Code Interpreter
    I recommend Visual Studio Code, but use your preferred one.

  2. Download and Install Python (>= 3.8)
    Make sure it is the correct bit version: Python 3.8

  3. Download and Install OpenSim (suggest >=4.3)
    OpenSim Downloads

  4. Install Rapid Env Editor (optional)
    Rapid Env Editor

  5. MOKKA (optional / only Windows users) Open-source and cross-platform software to easily analyze biomechanical data


Pip installation (testing...)

pip install msk_modelling_python

Test usage

import msk_modelling_python as msk

msk.greet()

Work with the code

  1. Create a Virtual Environment
    python -m venv msk
    
    Note: replace 'msk' if you want a different name

  1. Clone this Module "msk_modelling_python" to your virtual environment
    cd .\msk\Lib\site-packages
    
    git clone https://github.com/basgoncalves/msk_modelling_python.git
    
    Note: Ensure the name of the package is exactly "msk_modelling_python"

  1. Run OpenSim Setup from Installation Folder
    See OpenSim Scripting in Python
    .\msk\Scripts\activate
    cd 'C:\OpenSim 4.5\sdk\Python'
    python setup_win_python38.py
    python -m pip install .
    
    Note: run commands from shell or terminal

  1. Add the Path to the OpenSim Libraries to Your Environment Variables
    Add the following paths to your PATH variable:
    C:\OpenSim 4.5\bin
    C:\OpenSim 4.5\lib
    
    Note: see for help https://answers.microsoft.com/en-us/windows/forum/all/change-system-variables-on-windows-11/f172c29e-fd9e-4f0b-949d-c4696bd656b8

  1. Verify the OpenSim Installation (in python)
    import opensim as osim
    model = osim.Model()
    print("OpenSim model created successfully!")
    

  1. Install requirements (in the terminal)
    cd .\<myenv>\Lib\site-packages\msk_modelling_python
    pip install -r requirements.txt
    

  1. Testing msk_modelling_python (in python)
    import msk_modelling_python as msk
    msk.run_bops()
    
    Note: to change the performance of msk.run_bops() edit the settings file in .\msk_modelling_python\src\bops\settings.json

  1. Basic Usage
    import msk_modelling_python as msk
    
    # test msk
    msk.bops.Platypus().happy()
    
    # export c3d
    c3d_file_path = r'path\to\your\file.c3d'
    msk.bops.export_c3d(c3d_file_path)
    
    # run IK
    trial = msk.Project
    

  1. Use Example Scripts Use example scripts in the "ExampleScripts" directory to get started with common tasks and workflows.

This package includes a combination of other packages and custom functions to manipulate and analyze biomechanical data. Inspired by the MATLAB version of BOPS (Batch OpenSim Processing Scripts) - BOPS

Tools to be Included:


Code Structure

  1. msk_modelling_python This is the main package including all the modules needed for msk modelling, stats, data_processing, etc. This package contains subpackages that can be used independently.

  2. bops Batch Opensim Processing Software
    Package with functions and classes to use Opensim, CEINMS, stats, and others for easier processing.

  3. ui Functions to create user interface.

  4. osim commands


Examples

Find examples under ".\example_data\example_modules".
