  started_node_property,
  started_node_property_value,
  end_node_property,
  end_node_property_value,
  relationship_property_keys = NULL
)

## Not run: 
#Get the dataframe of relationships to be created
relationships = prepareRelationshipsDataframeToCreate(wntmully,nodes)

#Delete all relationships in the Neo4j database
for(row in 1:nrow(relationships)){
  removeRelationship(connection, "name", relationships[row,'V1'], "name", relationships[row,'V2'])
}

#Delete the relationships started from the node of name Complex10 and ended
in the node of name Protein1 in the Neo4j database
