Core techniques for analyzing biological rhythms:

Circadian rhythms are found in sleep cycles, body temperature, hormonal and enzymatic levels, even individual cells have circadian rhythms.  A majority of them are orchestrated by the brain through its endocrine controls.

These pages document core techniques for analyzing circadian rhythms, to extract period and phase and other key characteristics.  References on methodology and best practice are provided on the techniques from experts in the field.

A program that performs these analyses, called CAT, is documented as well.  CAT is a set of R routines. The analyses CAT performs are: actogram;  periodogram;  smoothing;  auto-correlation; cross-correlation; and a variety of cosinors, including a population mean cosinor.  Details on how to use CAT are also provided:  parameters, input data file format, output file naming and location, CRAN package,
