Figure 37 – Wear Time Validation Screen

What is a dataset and what are the limitations?

The Wear Time Validation tab performs screening on datasets. A single dataset represents a single device download

and may contain multiple days of data. Datasets are specific to a device and a user. If a user wears a device for five

days, recharges the device and wears it again for seven days, that user’s dataset will contain 12 days’ worth of data.

At this time, datasets cannot be concatenated. In other words, you cannot add data to a dataset. We are planning to

add this feature in a future release of ActiLife.

Adding Files (Datasets)

Datasets are added to the Wear Time Validation tab automatically after they have been downloaded in the Device” tab.

Alternatively, users can choose “Add Dataset” to select an individual AGD dataset to add to the tab. “Add Directory”

adds all the AGD files in a particular directory into the Wear Time Validation tool for processing. Removing datasets

works the same way. You can remove individual datasets by highlighting a dataset and clicking “Remove Selected

Dataset(s)” or remove all of the datasets and start again.

Filtering Data

Data filtering in the “Wear Time Validation” tab can be thought of as a three-stage process:

1 2 ... 56 57 58 59 60 61 62 63 64 65 66 ... 93 94
