What is the proper format for specifying a starting topology?
The tree should be contained in a separate file (with that filename specified on the streefname line of the configuration file) either in a Nexus trees block, or in standard Newick format (parenthetical notation). Note that the tree description may contain either the taxon numbers (corresponding to the order of the taxa in the dataset), or the taxon names. The tree can optionally contain branch lengths. As of version 0.96 it can also have polytomies. If multiple trees are contained in a single starting tree file, they will be used in order to start each successive search replicate (if searchreps > 1). See the streefname configuration entry for more details.
