Description

Setter Method for the PWMThreshold slot in a parameterOptions object

Usage

1
PWMThreshold(object) <- value

Arguments

object

object is a parameterOptions object

value

value is a numeric value (between 0 and 1) to be assigned to the PWMThreshold slot in parameterOptions object. Default is set at 0.7

Details

The computePWMScore function requires a so-called PWM Threshold. This threshold represents the Threshold at which PWM Score should be selected. The PWMThreshold is a positive numeric value (between 0 and 1. If set at 0, all sites will be selected. If set at 0.7 (Default value), then 70 % of PWM Score (and by extension binding sites) will be IGNORED. The top 30 % will be selected.

Value

Returns parameterOptions objetc with an updated value for the PWMThreshold slot
