 * **Scaled generic model**: a lower limb model was scaled linearly to the size of an individual to [perform a running simulation](https://simtk.org/projects/runningsim) as published by _Hamner et al. (2010)_. The muscle parameters of the [obtained model](https://github.com/modenaxe/MuscleParamOptimizer/tree/master/manuscript_material/Example1/MSK_Models) were then optimized non-linearly using the original generic model as reference model.
 * **Subject-specific model**: a [model of the lower limb](https://github.com/modenaxe/MuscleParamOptimizer/tree/master/manuscript_material/Example2/MSK_Models) was built from scratch using the LHDL cadaveric dataset and its muscle parameters were estimated and validated using the [lower limb model](https://simtk.org/projects/lowlimbmodel09) of _Arnold et al. (2010)_ as reference model.
 
-## MATLAB Scripts
-Following the alphabetic order of the scripts in the main folder, it is possible to:
+# Versions of the tool
+
+## MATLAB version
+
+A MATLAB version of the tool MATLAB tool is available in the [corresponding folder](https://github.com/modenaxe/MuscleParamOptimizer/tree/master/MATLAB_tool), together with an example of use. The same main script can be easily adapted for the optimization of other personalized models.
+
+For the MATLAB version, there is a [manuscript folder](https://github.com/modenaxe/MuscleParamOptimizer/tree/master/manuscript_material) including all the scripts and models from the publication. Following the alphabetic order of the scripts, it is possible to:
 * reproduce exactly the results presented in the associated publication in the manuscript (scripts a and b)
 * generate the associated Figures (scripts c-d-e).
 
 __Please note__ that reproducing the sensitivity study can be time-consuming, depending on the available computational resources.

+## OpenSim C++ plugin and User Interface Menu
 
 A generic tool to optimize musculotendon parameters in musculoskeletal models is also available at [this repository](https://github.com/MuscleOptimizer/MuscleOptimizer) as:
 * C++ OpenSim plugin 
 * as menu extension of the OpenSim GUI (graphical user interface).
 Please refer directly to the repository and to the nice documentation available at [this website](http://muscleoptimizer.github.io/MuscleOptimizer/).
