OxyMaxer is a cloud-based tool that helps to organize data into rows based on the type of measurement, and it sorts the data by subject ID. It also aligns the data according to the light-dark measurement, but if the lights do not switch off, it will sort the data by timestamp instead. It is important to double-check the data for accuracy. OxyMaxer also prints the animal weights and test chamber assignments (by date) at the top of the sheet.
