WebThe (approximate) formula is: #false-positives/promoter = (2 * promoter length) * p -value threshold. If your promoters are longer than 1000bp, you would need to decrease the p -value threshold to compensate. For 5000bp promoters, you would need to divide the p -value threshold by five, giving a threshold of 0.00002.
