# Adding a Trajectory

Add a POF trajectory from InertialExplorer or NavLab Embedded. RiProcess will convert this to a POFX format:

Select Yes and follow the prompts. All default settings are acceptable with POFX conversion. You should see that the POFX was created successfully:

One complete, click Quit and add the trajectory to the project by clicking Continue.&#x20;

Once the trajectory is added to the project, edit the top level project settings and compute region of interest from the trajectory:
