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.
Returns the value assinged to the PWMThreshold
