Research tools

The SRBR Education Committee has compiled a list of resources that allow students and researchers to seek answers to new questions related to biological rhythms. This includes links to open access datasets that may support student-directed research as well as data analysis tools that may help in the analysis of these data sets.

Open Access data sets

  • CATkit, this website documents core techniques for analyzing circadian rhythms and describes the CAT analysis toolkit that can be used to perform these analyses. The CAT package was developed by Gierke and Cornelissen  (2016).
  • JTK_Cycle, an algorithm to identify rhythmic components in large, genome-scale data sets and estimate their period length, phase, and amplitude, developed by Hughes et al. (2010).
