 The processing done in Visual3D allows us to extract signal traces from all of our desired gait sequences from the .c3d files, but not all of these are suitable for further analysis. The number of traces involved makes it impractical to clean this data set in Visual3D, there are more than 3000 traces for Participant 1 alone, but Sift gives us the ability to visualize the ground reaction forces and make inclusion/exclusion decisions for each trace. A detailed explanation of this process can be found in the [[Sift:Tutorials:Clean_your_Data|Clean your data]] tutorial.

 Now that Participant 1's CMZ file has been cleaned of any unwanted traces, we are ready to perform some preliminary analysis and visualize the data set. Our goal in this section is to reproduce [[https://www.nature.com/articles/s41597-022-01817-1/figures/3|Figure 3]] in the paper.
