Description
Counts the number of extra lineages contributed by a species tree and a set of gene trees. The trees must be specified in the rich newick format Rich Newick Format. Specifying more than one species three tree will run the command multiple times with one execution per species tree.
Usage

| ||
DeepCoalCount_tree {species_tree_ident1 [, species_tree_ident2...]} {(gene_tree_ident1 [, gene_tree_ident2...]}) [-u] [-b threshold] [-a taxa map] [result output fileresultOutputFile] |
species_tree_ident1 [, species_tree_ident2...] | Comma delimited set of species tree identifiers. | mandatory |
gene_tree_ident1 [, gene_tree_ident2...] | Comma delimited set list of gene tree identifiers. See details. | mandatory |
-u | Gene trees should be treated as unrooted. | optional |
-b threshold | Gene tree bootstrap threshold. Edges in the gene trees that have support lower than thresholdwill be contracted. | optional |
-a taxa map | Gene tree / species tree taxa association. | optional |
result output file resultOutputFile | Optional file destination for command output. | optional |
...
By default, it is assumed that only one individual is sampled per species in gene trees. However, the option [-a taxa map]
allows multiple alleles to be sampled.
