How to get Ground Truth time stamp labels from NAB data

[Hiteshsaai]

We are working on a anomaly detector model, and we are using NAB data to evaluate the performance. But we are unclear about how to run the performance metrics to evaluate on the NAB data. For example how to calculate the following ?
Standard Profile
Reward Low FP
Reward Low FN

Do you have any script or CLI tool to run our results on it to get the metrics? Kindly help me out

Below i am attaching sample screenshot of our results for reference, to help us with interpreting with ground truth
