Gets all pairs of nodes with TimeTree info for all nodes.

Compute all pairs of leaves that could provide information about the divergence time of an ancestral node.

Usage

getTimeTreePairs(nodes, tree, ncbi_ids_timetree)

Arguments

nodes

A list in which each element corresponds to an ancestral node. Each element was computed with the function getLeaves and consists of a named list that maps the ID of each direct descendant node to the IDs of its descendant leaves.

tree

A ConvenientTblTree object.

ncbi_ids_timetree

A list of NCBI ids that appear in the TimeTree database.

Value

A named list that maps each ancestral node to pairs of leaves, identified by their node IDs. These pairs of leaves are informative for estimating the divergence time of that ancestor.
