Hi folks,I am attempting to get a subgraph and graph data(as '.txt 'or other formats) from a big graphApproach 1: Randomly sample all nodes types from the large graph MATCH (source: Node)-[r*..]-(target: Node) WHERE source.name<>target.name WITH so...

Hi, great minds! I am new to neo4j and currently exploring an existing graph to extract data for downstream tasks.I would like to get all pairs of nodes and their relationship from the graph. MATCH (n)-[r]-(n1) WHERE n<>n1 AND n1>n RETURN * This wil...

I deeply appreciate your help, maybe a few more lines here could clarify my issues: Say I have allsimplepaths(A, B, '', 3) that look like this: [A –>relation1 –>B][A –>relation2 –>B][A –>relation2->C->relation 1–>B][A –>relation5->D->relation 3–>B][A...

For instance:I have a network from CREATE (a:Node {name: 'mola', type: 'Molecule'}) CREATE (g:Node {name: 'molg', type: 'Molecule'}) CREATE (b:Node {name: 'drgb', type: 'Drug'}) CREATE (h:Node {name: 'd...

Actually, the match is between 2 node types, not the whole db. MATCH p = (n:Node{type: 'typeA')-[*1..2]-(n1: Node(type: 'typeB') This is so helpful! I haven't explored SKIP and LIMIT use before RETURN. Thanks a bunch for that.

I noticed that the query gives only the first-order connection between 2 nodes; however, I will need at least the second-order relationship for my downstream application. I have tried:MATCH (n)-[r*1..2]-(n1) WHERE n<>n1 AND id(n)<id(n1) WITH n.name...

The API does the trick! I'm so happy right now.Thank you so much @bennu_neo, for your help. It means a lot!
