The PhyloToAST project is a collection of python code and scripts that modify the QIIME [1] pipeline by adding/changing several steps including: support for cluster-computing, multiple primer support (eliminate primer bias) [2], enhanced support for species-specific analysis, and additional visualization tools.


To install PhyloToAST from PyPI:

$ pip install phylotoast

From source:

$ python install


Full documentation for the scripts and code is available at the PhyloToAST documentation site


The list of required modules will vary depending on which executable scripts and/or parts of the API you may use. For this reason there are no required dependencies that will be automatically installed along with PhyloToAST. Each executable script will check that the required libraries are installed and will print a message if any are not found.

If you would like to install everything up front, the following is a complete list of libraries that are used in PhyloToAST:

  • numpy
  • scipy
  • matplotlib >= 1.5.0
  • biopython >= 1.60
  • scikit-bio
  • scikit-learn
  • pandas
  • statsmodels
  • brewer2mpl
  • biom-format >= 2.1.5
  • h5py (for parsing BIOM v2.x format files)


The PhyloToAST source is hosted on github.
