• The script run starts after the acquisition together with the online image analysis. Therefore, the script execution, image analysis and writing of the image subblock to the hard drive are not in sync.
  
• The online image analysis starts after the acquisition of a frame is finished. Only when the image analysis is finished, the next script run is triggered. This guarantees that all analysis results exist and can be used in the feedback script. The writing to disk is not synchronized.
  
• The online image analysis starts after the acquisition of a frame is finished. The image data are written to disk and only when all tasks are finished the next script run is triggered. This guarantees, that all analysis results exist and the image data is stored on disk before the next script run is triggered. This option is relevant in case the script starts an external application to analyze the data.
