Methods

findIslands()

public findIslands(DnaSequence $oSequence[, int $iWindowSize = 200 ][, int $iStep = 1 ][, float $fMinGcContent = 0.5 ][, float $fMinObservedToExpectedRatio = 0.6 ]) : array<string|int, CpGIsland>
Parameters
$oSequence : DnaSequence
$iWindowSize : int = 200
$iStep : int = 1
$fMinGcContent : float = 0.5

0.5 = 50%, the usual Gardiner-Garden & Frommer threshold

$fMinObservedToExpectedRatio : float = 0.6

0.6, the usual threshold

Return values
array<string|int, CpGIsland> —

In ascending order of start position, never overlapping
