The MoPS package implements the model-based periodicity screen as used in Eser et al.(Mol Syst Biol, 2014) for the detection and characterization of periodic genes.
Function that fits periodic curves to each time course in a numeric matrix or ExpressionSet object. It determines the best fitting time courses from an exhaustive set of periodic and non-periodic test functions. These are created either automatically or with a user-specified parameter set (see Arguments). Fitting is done with standard linear regression.
