-=== Square Brackets ===
 Square Brackets **[** and **]** specify frame numbers and components
 Square Brackets **[** and **]** are used at the end of a function call or parenthesis ( ) to specify the frames numbers and components
 Example, add two signals and retrieve the component 1 from frame 5

 whenever the z-component of a marker is less than a threshold (e.g. 0.08 in this example)
 otherwise set the resulting frame to NO_DATA
