void TreeTools::computeBranchLengthsGrafen	(	Tree &	tree,
		double	power = `1`,
		bool	init = `true`
	)

static

Compute branch lengths using Grafen's method.

The 'height' of each node is divided by the total height of the tree, and the ratio is raised at power 'rho'. A value of rho=0 hence returns a star tree.

Reference: Grafen A. The phylogenetic regression. Philos Trans R Soc Lond B Biol Sci. 1989; 326(1233):119-57

Parameters

tree	The tree to use.
power	The rho parameter.
init	Tell if the height must be initialized by calling the initBranchLengthsGrafen() method. Otherwise use branch lengths.

Exceptions

◆ constrainedMidPointRooting()

void TreeTools::constrainedMidPointRooting ( Tree & tree )

static

Determine the mid-point position of the root along the branch that already contains the root. Consequently, the topology of the rooted tree remains identical.

This code uses two inner functions to compute the mid-point position: statFromNode_ and bestRootPosition_. This code is inspired by a code performing a similar calculation in Seaview (Guindon et al., 2010, Mol. Biol. Evol. 27(2):221-4).

Parameters

tree	The rooted tree for which the root has to be moved to its mid-point position, along the branch where it already stands.

◆ convertToClockTree()

double TreeTools::convertToClockTree	(	Tree &	tree,
		int	nodeId,
		bool	noneg = `false`
	)

static

Modify a tree's branch lengths to make a clock tree, by rebalancing branch lengths.

The height of each node is set to the mean height of all son nodes. This may however lead to negative branch lengths, since the mean height may be inferior to one of the son heights, due to short branch lengths. If the 'noneg' is set to yes, the mean height is checked against all son heights. If it is inferior to one of the son heights, the maximum son height is used instead. This results in a multifurcation.

This method is recursive and will be applied on all sons nodes.

Parameters

tree	The tree to use.
nodeId	The node defining the subtree.
noneg	Tell if the correction for non negative branch lengths must be used.

Returns: The modified height of the node.

Exceptions

NodeNotFoundException	If the node is not found.
NodeException	If one branch length is lacking.

◆ convertToClockTree2()

double TreeTools::convertToClockTree2	(	Tree &	tree,
		int	nodeId
	)

static

Modify a tree's branch lengths to make a clock tree, by rescaling subtrees.

The height of each node is set to the mean height of all son nodes. All branch lengths of the corresponding subtrees are updated proportionally. This algorithm is smaller than the convertToClockTree method, but may be more accurate.

This method is recursive and will be applied on all sons nodes.

Parameters

tree	The tree to use.
nodeId	The node defining the subtree.

Returns: The modified height of the node.

Exceptions

NodeNotFoundException	If the node is not found.
NodeException	If one branch length is lacking.

Calls thresholdConsensus with threshold=0, i.e. no constraint on the number of occurrence of bipartitions. The resulting tree is fully resolved.

Author: Nicolas Galtier

Parameters

◆ initBranchLengthsGrafen() [1/2]

void TreeTools::initBranchLengthsGrafen ( Tree & tree )

static

Grafen's method to initialize branch lengths.

Each height of the node (total distance from the leaves) is set equal to the number of leaf nodes for the corresponding subtrees - 1 for inner nodes, 0 for leaves.

If the tree already has branch lengths, they will be ignored.
