## About Vicon ProCalc

ProCalc is a software application that makes it easy to develop, implement, test and routinely run biomechanical models calculating kinematic variables, parameters and events. ProCalc is based on a graphical user interface (GUI), and does not require the use of a script language. 

This guide aims to demonstrate how to build a basic biomechanical model.

The following information is included:

About the data for this tutorial

To follow this tutorial, navigate to *C:\Program Files\Vicon\ProCalc\Help* and unzip the *ProCalc Tutorials Data* file. Choose a path or directory that has sufficient read/write permissions and that you can remember and access easily (e.g. *C:\Users\Public\Documents\Vicon*). If you have completed a ProCalc tutorial in the past, you may have already completed this step.


    For this tutorial, we will use the *Getting Started*
     session. Within this folder, there is one trial (*Walking01.c3d*).


To access the trials in ProCalc, ensure you have a hierarchy that looks like the following example, though the specific path will depend on the location of your extracted data.
