PySurvey: Interactive analysis of survey data 
**********************************************

``PySurvey`` is a `Python <http://www.python.org>`__ package designed to perform interactive analysis of survey data, composed of counts of occurrence of different categories in a collection of samples. 
Specifically, ``PySurvey`` is developed in the context of genomic surveys, such as 16S surveys, where one studies the occurrence of OTUs across samples.
Though much of ``PySurvey``'s functionality is not unique to survey data, and equivalent features are implemented in many other packages, ``PySurvey`` is intended to serve as a 'one-stop-shop', and thus attempts to includes all the methods that are commonly used in the analysis of genomic survey data (often by wrapping around other packages), with a sensible choice of default parameters (e.g. distance metrics, etc').

``PySurvey`` is based on the powerful `pandas <http://pandas.pydata.org/>`__ package which offers rich data structures which are 
tailored and optimized for interactive analysis of large data tables.
