Description
The Reactome definition of events includes pathways and reactions. Although events are organised in a hierarchical structure, a single event can be in more than one location, i.e. a reaction can take part in different pathways while, in the same way, a sub-pathway can take part in many pathways. Therefore, this method retrieves a list of all possible paths from the requested event to the top level pathway(s).
