**What it does**

This tool implements a Maximum Likelihood (ML) fossil placement algorithm developed by Berger and Stamatakis 2009. 

------

**Inputs**

1. Input file of morphological data in raxml (phylipE) format. In Osiris, this can be generated by exporting a MorphoBank (www.morphobank.org) dataset into TNT format, then using TNT2PHYTAB, followed by phylocatenator to change the data to raxml format.
2. A molecular phylogeny in nexus format, for example the result of a RAxML analysis.

------

**Outputs**

RAxML writes the resulting tree file in newick text format, which can be viewed in Osiris with TreeVector (of the mothur package). In addition, if bootstrapping was selected, the individual bootstrap trees and the ML tree with support are written as separate newick files.

-------    

**Additional Information**

This method assumes a molecular phylogeny for a set of extant taxa, and then generates weights for each morphological character based on congruence with the molecular phylogeny.  Next, the method attaches the fossils to every possible branch of the molecular tree, and in each case calculates the likelihood of observing the weighted morphological data.  The placement of each fossil in the molecular tree is the placement with the maximum likelihood estimate.
