  <help><![CDATA[Identify exogenously acquired compounds, exogenously available producible compounds and/or dead ends metabolites from metabolic network topology
Metabolic seeds and targets are useful for identifying medium requirements and metabolic capability, and thus enable analysis of metabolic ties within communities of organisms.
This application can use seed definition and SCC-based detection algorithm by Borenstein et al. or, alternatively, degree-based sink and source detection with compartment adjustment.
The first method (see Borenstein et al. 2008 Large-scale reconstruction and phylogenetic analysis of metabolic environments https://doi.org/10.1073/pnas.0806162105) consider strongly connected components rather than individual nodes, thus, members of cycles can be considered as seeds. A sink from an external compartment can however be connected to a non sink internal counterpart, thus highlighting what could end up in the external compartment rather than what must be exported.
The second approach is neighborhood based and identify sources and sinks. Since "real" sinks and sources in intracellular compartment(s) may be involved in transport/exchange reactions reversible by default, thus not allowing extracellular source or sink, an option allows to take the degree (minus extracellular neighbors) of intracellular counterparts.]]></help>
