**What it does**

SHtest performs the Shimodaira-Hasegawa statistical test to compare one tree topology to alternative tree(s). The test is implemented with RAxML.

------

**Inputs**

#. A file in RAxML (phylipE) format. This can be made with Osiris tools phylocatenator or fasta2phylipE. 
#. Model of evolution assumed for likelihood calculations.
#. An optional RAxML partition file delineates data set partitions. This can be made with Osiris tool phylocatenator.
#. Target phylogeny in newick format.
#. Alternative hypothesis phylogenetic tree(s) in newick format.

------

**Outputs**

The output is text output from RAxML, which details the statistical value of the SH test(s).
