RAxML is a phylogenetics code that uses the Maximum likelihood model of molecular evolution. Similar to MrBayes code, it computes a likelihood score that depends upon tree topology, branch lengths and parameters for model.


To use RAxML, simply load the module:

module load raxml
There are 4 different binaries to choose from:
  • raxmlHPC - serial
  • raxmlHPC-SSE3 - serial version that exploits fine-grain parallelism in processor
  • raxmlHPC-PTHREADS - parallel version
  • raxmlHPC-SSE3-PTHREADS - parallel with vector instructions
When using the parallel versions, specify the number of threads with the -T option.
