For a step-by-step example of performing PCA in Sift, see [[Sift:Principal_Component_Analysis:Using_Principal_Component_Analysis_in_Biomechanics#Tutorials|here]].

The Run PCA Dialog {{:sift_run_pca.png?30}} can be found on the main toolbar in Sift. This dialog allows you to generate new PCA results with custom names for selected data in Sift.

The options are as follows:

**PCA Name:** The name chosen for the PCA. \\
**Number of PC's:** How many PC's you wish to display for the [[Sift:Application:Analyse_Page#Variance_Explained|Variance Explained]]. Defaults to 4. \\
**Use workspace mean:** Lets you decide whether you want the mean workspace signals of the selected data to be used for you PCA analysis or not (which will use the raw traces). \\
