Reading data
To extract data once recording is complete:
1 Open the GENEActiv software and connect the charging cradle to a USB port. Insert a GENEActiv device into
the cradle. Click ‘Data Extractor’ from the lefthand menu. This page previews the first few minutes of recorded
data and allows you to download data to a chosen file location.
2 Chose a file location and select whether to also create a .csv format file. The default data format is a
compressed .bin that can be interpreted, with a suitable script, by most mathematical analysis software
packages, but not Excel. A .csv format file is readable by Excel but can be unwieldy if there is a large amount
of data. The Data Converter and Data Analysis tabs (selected from the left-hand menu) can convert .bin files to
.csv files or to compressed .csv files that can be handled more easily. This means that .bin files can be saved
and then converted to another format at a later date if required.

Click the ‘Extract’ button. The data can take up to 20 minutes to download and a pop-up will
confirm completion.
Data Converter and Data Analysis
The ‘Data Converter’ creates .csv files, which can be used by Excel, from .bin files. Please note that older versions
of Excel cannot manage very large .csv files.
The ‘Data Analysis’ tab has a viewer which allows data from .bin and .csv files to be previewed. There is an option
to look more closely at sections of the data. The ‘Epoch Converter’ can be used to turn .bin and large .csv files into
a smaller compressed version. It does this by creating epochs of 1, 5, 10, 15, 30, or 60 seconds – the means for
each parameter and the Sum Vector Magnitude are calculated for each epoch.
