Light controller measures
 | ANY-maze has been designed to be extended, and we'll be delighted to add any new measures you might find useful, for free! Just contact ANY-maze Support. |
ANY-maze will score the following measures for a light controller:
Each measure is available for the apparatus as whole (i.e. irrespective of where the animal was when the light controller activation occurred), and also for each defined zone.
Number of activations
| Description | Reports the number of times the light controller was activated. |
| Calculation method | Counts the number of activations. |
| Analysis in zones | Counts the number of activations when the animal was in the zone. |
| Analysis across time | This measure can be analysed across time. For any time period, the result is the number of activations during the time period. |
Time active
| Description | Reports the total amount of time that the light controller was active. |
| Calculation method | Sums the amount of time for which the light controller was active. |
| Analysis in zones | Sums the amount of time for which the light controller was active while the animal was in the zone. |
For a particular zone, it's possible for the Time active to be non-zero while the Number of activations is zero. This can occur if the animal enters the zone when the light controller is active. In this case, the time the light controller is active will be registered but the activation itself won't be.
| Analysis across time | This measure can be analysed across time. For any time period, the result is the amount of time that the light controller was active during the period. |
For a particular time period, it's possible for the Time active during the period to be non-zero while the Number of activations for the period is zero. This can occur if the light controller is already active at the start of the period. In this case, the time the light controller is active will be registered but the activation itself won't be.
Latency to first activation
| Description | Reports the amount of time that elapsed in the test before the light controller was activated for the first time. |
| Calculation method | The value of the test clock at the first activation of the light controller. |
| Analysis in zones | The value of the test clock at the first activation of the light controller that occurred while the animal was within the zone. |
| Analysis across time | This measure cannot be analysed across time. |
Latency to first deactivation
| Description | Reports the amount of time that elapsed in the test before the light controller was deactivated for the first time. |
| Calculation method | The value of the test clock at the first deactivation of the light controller. |
| Analysis in zones | The value of the test clock at the first deactivation of the light controller that occurred while the animal was within the zone. |
| Analysis across time | This measure cannot be analysed across time. |
Longest activation
| Description | Reports the duration of the longest period for which the light controller was continuously active. |
| Calculation method | The duration of each light controller activation is calculated and the largest value is found. |
| Analysis in zones | The longest period for which the light controller was continuously active while the animal was in the zone. |
| Analysis across time | This measure can be analysed across time. For any time period, the result is the longest period for which the light controller was continuously active during the period. |
Shortest activation
| Description | Reports the duration of the shortest period for which the light controller was continuously active. |
| Calculation method | The duration of each light controller activation is calculated and the smallest value is found. |
| Analysis in zones | The shortest period for which the light controller was continuously active while the animal was in the zone. |
| Analysis across time | This measure can be analysed across time. For any time period, the result is the shortest period for which the light controller was continuously active during the period. |
Average activation duration
| Description | Reports the average duration for which the light controller was active. |
| Analysis in zones | This measure cannot be analysed in zones. |
| Analysis across time | This measure cannot be analysed across time. |
Frequency of activations
| Description | Reports the frequency with which the light controller was activated. |
| Analysis in zones | Calculated by dividing the Number of activations in the zone by the Total time in the zone. |
| Analysis across time | This measure can be analysed across time. For any time period, the result is the Number of activations which occurred during the period divided by the period's duration. |
