You should use a positive real number greater than 1. Please see the documetation from the phylip package for more information. .SS OUTGROUP .IX Subsection "OUTGROUP" Title : OUTGROUP Description : (optional) .PP .Vb 4 \& This specifies which species is to be used to root \& the tree by having it become the outgroup. Input \& values are integers specifying which species to use. \& Defaults to 1 .Ve .SS JUMBLE .IX Subsection "JUMBLE" Title : JUMBLE Description : (optional) This enables you to tell the program to use a random number generator to choose the input order of species. Input values is of the format: seed,iterations eg 17,10 seed: an integer between 1 and 32767 and of the form 4n+1 which means that it must give a remainder of 1 when divided by 4. Each different seed leads to a different sequence of addition of species. By simply changing the random number seed and re-running programs one can look for other, and better trees. iterations: For a value of 10, this will tell the program to try ten different orders of species in constructing the trees, and the results printed out will reflect this entire search process (that is, the best trees found among all 10 runs will be printed out, not the best trees from each individual run). .SH FEEDBACK .IX Header "FEEDBACK" .SS "Mailing Lists" .IX Subsection "Mailing Lists" User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated. .PP .Vb 2 \& bioperl\-l@bioperl.org \- General discussion \& http://bioperl.org/wiki/Mailing_lists \- About the mailing lists .Ve .SS Support .IX Subsection "Support" Please direct usage questions or support issues to the mailing list: .PP \&\fIbioperl\-l@bioperl.org\fR .PP rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible. .SS "Reporting Bugs" .IX Subsection "Reporting Bugs" Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution.
