What is the QC parameter Ratio Hardware IO events?
Last Updated 3 years ago

This number is the ratio of events triggered by the software and the actual number of hardware events. For the CognitionWall experiments this is the number of commands given by EthoVision to drop a pellet versus the actual number of pellets dropped by the pellet dispenser. If this is less than 0.95 (i.e. EthoVision gave 100 commands, but the Pellet Dispenser only dropped 94), then this file is not used for data analysis. This can be caused by for example a clogged pellet dispenser or when the pellet dispenser is empty.
