Using Neo4j plug-in to create relationships duplicates nodes
Hi,
I have created unique identifier(s) for two types nodes in my graph. I first push the data on the nodes into Neo4j, using Export nodes recipe: Primary key is set to a column containing the unique identifier for the node. Then I push the data using the Export relationships recipe. Primary keys for source and target are set to the columns containing the same unique identifiers that were previously specified for the nodes. After I push the relationship data, the number of nodes used as target and source have been duplicated in Neo4j. Any ideas on how I can merge the nodes or avoid duplication without resorting to cypher queries? Thank you for your help!
Lina.
P.S. I have looked at Drug Repurposing project but I cannot identify the problem with my own setup.
