# Run Mode

PatMax supports two run modes for locating the pattern in each acquired image. By default, PatMax uses Search Image mode and searches the entire image for the pattern it is trained to find. PatMax also supports Refine Start Pose mode, which limits the search for the pattern to within a few pixels of a defined starting position, typically supplied by another vision tool. Using Refine Start Pose mode, PatMax does not use its coarse granularity settings to search the image for larger features, and instead moves to a refined search for the smaller features assuming they are located within an extremely narrow range of the given starting position.
