HDF5-graph

What are we going for?

• circle is node
• round edges is node with neo4j datatype
• rectangle is property

mindmap
  root((mindmap))
    ((grp1))
        ((BF_curves))

        ((feap_variables))
            id2(ca)

Example Cypher Queries

Return all datapoints hdf5 paths where ca=0.3

MATCH (d:Dataset{name:"datapoint"})-[]->(e:Experiment)-[]->(c:Dataset{name:"ca",value:0.3})
RETURN d.hdf5_path

Return all datapoints hdf5 paths where ca=0.3 and which were identified as the first curve

MATCH (d:Dataset{name:"datapoints"})<-[:holds]-(e:Experiment)-[:holds]->(c:Dataset{name:"dt",value:0.00025})
WHERE d.hdf5_path CONTAINS "Curve_1"
RETURN d.hdf5_path

Rules:

• top groups are experiments
