The development of the R-package to automatically convert raw actiwatch data to usable variables
Actigraphy is more and more used in research. Also within the iLab several different studies in which actigraphy was used are ongoing and finished. Actigraphy is a relatively non-invasive method to measure sleep, circadian (24hrs) rhythm and physical activity in daily life. However, two problems of the conversion of raw actigraphy data to usable variables are: 1) it is a time-exhausting process, and 2) it is less easy to replicate because you are dependent on software packages belonging to the actiwatch which are prone to updates and removal. Therefore, Yoram Kunkels (PhD student at the ICPE), Stefan Knapen (PhD student at the ICPE) and Ando Emerencia (post doc researcher at the RuG) are currently developing the R-Package ACTman. ACTman automatically converts raw actiwatch data into usable variables for sleep, circadian rhythm and perhaps in a later stage also physical activity.
Any researcher who uses actigraphy and is interested in using the R-package can contact Yoram, Stefan or Ando for questions and personal wishes concerning the R-package. Their e-mail addresses are: firstname.lastname@example.org; email@example.com; firstname.lastname@example.org.
