Species METabolic interaction ANAlysis (SMETANA) is a python-based command line tool to analyse microbial communities.
It takes as input a microbial communtity (from a collection of genome-scale metabolic models in SBML format) and computes of several metrics that describe the potential for cross-feeding interactions between community members.
