The Intercom /cypher command will download checked Beam entries as a .cypher file that will create or merge nodes and relations using Cypher query language commands. See Using the Intercom Pane
Nodes are written as merge clauses that bind temporary names n0, n1, etc, to the merged or created node.
merge (n0:Variable {name:"Prey",value:100,wax:0.3}) merge (n1:Variable {name:"Pred",value:10,wane:0.1})
Relations are written in terms of these bound temporary names, again merging or creating as needed.
merge (n1)-[:Decreases {irate:0.1,orate:0.1}]->(n0) merge (n0)-[:Increases {irate:0.002,orate:1}]->(n1)
