For who:

  • Anyone interested in using GGIR to process wearable accelerometer data.
  • No prior experience is required with accelerometry, physical activity, or sleep research.
  • No prior experience with R or programming is required, although we strongly recommend that you go through our short R tutorial (approximately 15 minutes) which teaches you the basics of R needed to get started with GGIR.

Course location:

All training sessions take place online. You will receive a Zoom link via e-mail at the end of the booking process. We will do our best to choose optional course times that are friendly to all sides of the globe. If you do not see a timeslot that aligns well with your time zone then please let us know.

If you would like us to provide the training in person at your research site then we may in specific circumstances be able to accommodate this at a higher fee. Generally speaking, we try to avoid abundant travelling to save time and the planet. Please contact us if you are interested.

Requirements:

  • A computer (macOS, Windows, Linux) with at least 5GB space to store files and process data. We are not using cloud services because we think it is important that you directly familiarise yourself with using GGIR on your own computer.
  • Installed version of R and RStudio. No prior knowledge of R or RStudio is requiredalthough we strongly recommend that you go through our short R tutorial (approximately 15 minutes) which teaches you the basics of R needed to get started with GGIR.

Suggestions (not required):

  • Working with two screens can be beneficial to follow the course on one screen and to try out GGIR on the other screen.
  • Although we will provide example data, it can be helpful to also prepare a sample of your own research data.

Payment:

You will be prompted with a payment instruction at the end of the booking process. We accept PayPAL, Credit card, and Debit cards. You do NOT need a PayPal account to pay with Credit card: Scroll down on the payment form for the Credit card option. If a payment is not received within 30 minutes the booking will be cancelled.
