Accessor Method for the noOfSites slot in a genomicProfileParameters object

Description

Accessor Method for the noOfSites slot in a genomicProfileParameters object

Usage

noOfSites(object)

Arguments

Details

While computing Position Weight Matricies (PWM) from Position Frequency Matricies (PFM), it is possible to restrict the number of sites that will be used to compute the PWM. The default is set at 0. In this case, all sites will be used to compute the PWM.

Value

Returns the value assigned to the noOfSites slot in a genomicProfileParameters object.
