Class GraphvizWalker

java.lang.Object
  edu.upenn.cis.spinal.AbstractWalker
      edu.upenn.cis.spinal.GraphvizWalker

public class GraphvizWalker
extends AbstractWalker

Walks through a treebank, reads it in, and outputs representations of the trees in Graphviz format. Alternatively, selects a given sentence (identified by its location) in the treebank and outputs a Graphviz representation for that sentence.

 Usage: java edu.upenn.cis.spinal.GraphvizWalker <infile> [<sentence_location>] 
 Output will be placed in files named <sentence_location>.dot.
 If <sentence_location> is not given, then all the sentences in the file will be processed and placed into a separate file each.
