BEAST v2.5.0 Documentation: beast.evolution.operators.SubtreeSlide

Proposes a move in state space.
This operator changes a beast.tree.
Moves the height of an internal node along the branch. If it moves up, it can exceed the root and become a new root. If it moves down, it may need to make a choice which branch to slide down into.

Inputs:

size, gaussian, optimise, limit, tree, markclades, weight

 

size
type: java.lang.Double
size of the slide, default 1.0
Optional input. Default: 1.0

 

gaussian
type: java.lang.Boolean
Gaussian (=true=default) or uniform delta
Optional input. Default: true

 

optimise
type: java.lang.Boolean
flag to indicate that the scale factor is automatically changed in order to achieve a good acceptance rate (default true)
Optional input. Default: true

 

limit
type: java.lang.Double
limit on step size, default disable, i.e. -1. (when positive, gets multiplied by tree-height/log2(n-taxa).
Optional input. Default: -1.0

 

tree
type: beast.evolution.tree.Tree
beast.tree on which this operation is performed
Required input

 

markclades
type: java.lang.Boolean
Mark all ancestors of nodes changed by the operator as changed, up to the MRCA of all nodes changed by the operator.
Optional input. Default: false

 

weight
type: java.lang.Double
weight with which this operator is selected
Required input
