The next step after retrieving your data is to begin analyzing it. The first step in this process is to validate the data for Wear and Non Wear-time. Wear-Time Validation (also known as WTV) is the method by which ActiLife flags Epoch data as Wear-time (i.e. yes, the device was being worn and the subject was doing stuff) or Non-Wear time (i.e. no, the device was not being worn or the subject was not doing anything). This is achieved by applying an internally developed algorithm along with other customizable criteria to the dataset. We will not go into detail about what each of these criteria are here but you can find out more about them by viewing the FAQ articles posted here.
On the left side of this tab, you will see the various criteria that you can adjust for your specific study (in most instances the defaults are fine). The buttons along the top of this tab allow you to add or remove Dataset(s). Simply clicking on the Calculate button will analyze the dataset using the selected criteria. You can use the scroll bar at the bottom of the window to see the results for the entire dataset. If you would like to view the results down to the Epoch level, click on the details button next to the dataset.
This takes us to the next tool in ActiLife; the Data Scoring tab. Click here to continue.
