%description
A new pipeline to explore chemical structural similarity across
metabolites. It allows the metabolite classification in
structurally-related modules and identifies common shared functional
groups. The KODAMA algorithm is used to highlight structural similarity
between metabolites. See Cacciatore S, Tenori L, Luchinat C, Bennett PR,
