NAME
Text::Tradition::StemmaUtil - standalone utilities for stemma graph display and distance tree calculations
DESCRIPTION
This package contains a set of utilities for displaying arbitrary stemmata and running phylogenetic analysis on text collations.
SUBROUTINES
read_graph( $dotstr) {
Parses the graph specification on the filehandle in $dotstr and returns a Graph object. This subroutine works around some deficiencies in Graph::Reader::Dot.
display_graph( $graph, $opts )
Returns a dot specification intended for display, according to the logical attributes of the witnesses.
editable_graph( $graph, $opts )
Returns a dot specification of a stemma graph with logical witness features, intended for editing the stemma definition.
character_input( $tradition, $opts )
Returns a character matrix string suitable for Phylip programs, which corresponds to the given alignment table. See Text::Tradition::Collation for a description of the alignment table format. Options include:
exclude_layer - Exclude layered witnesses from the character input, using only the 'main' text of the witnesses in the tradition.
collapse - A reference to an array of relationship names that should be treated as equivalent for the purposes of generating the character matrix.
phylip_pars( $character_matrix )
Runs Phylip Pars on the given character matrix. Returns results in Newick format.
parse_newick( $newick_string )
Parses the given Newick tree(s) into one or more Stemma objects with undirected graphs.
newick_to_svg( $newick_string )
Uses the FigTree utility (if installed) to transform the given Newick tree(s) into a graph visualization.
