This program will compute the circadian period of a time series and will
determine the statistical significance of the computed period.
The program is an implementation of the chi-square periodogram procedure
(see references on the right panel). Equally-spaced data sets (with one
measurement per line) are expected. The time of day when the data set starts
The resolution of the computed period will depend on the resolution
(bin size) of your data. For a resolution of 0.1 hour, you need a
bin size of 6 minutes.
Regardless of the resolution of the computations, the test of significance
(used to determine whether the computed period is statistically significant) assumes
that you have at least 10 days of data. With fewer days, the computed value will still be accurate,
but the significance test will be less sensitive.
