We have developed a model for data processing in neo4j. These are the nodes :Experiment , :Variety , :Compound , :Parameter and the relationships between them. To specify from which variety is the value of the parameter we specified the paid property...

Error by using Pearson Similarity algorithm. Indicates 3 arguments, but there are 2 ('params' and 'rel.weight') MATCH(knop:Compound{prep:'Control'})-[rel:HAS]->(params) WITH knop, gds.alpha.similarity.asVector(params, rel.weight) AS cVector MATCH(p1h...

There are several nodes: Variety. Each node is connected with the nodes :Control (no treatment applied), :P1R - one treatment is applied and :P2B another treatment is applied. Each node ( :Control, :P1R, :P2B) is connected to the :Protein node by the...

I'm defining the relationship between two entities, Variety and Treatment. match (s1:Variety),(c:Treatment) where id(s1)=0 and id(c)=4 create (s1) - [rel:UNTREATED]-> (c) return type(rel) Result is '(no changes, no records)'. In this context, an erro...

What is the difference from temporal operators vs temporal functions?

Thank you very much for your help. The same nodes (Control, Biovit, Reglalg etc.) must be processed for each experiment :Variety and :Parameters. I think I'll use the model you proposed.

Thank you very much for your help and I apologize for the inconvenience. It is the best model, but I want to add other varieties and it is not clear to which varieties the parameters refer. I have modified it in several ways but there are errors. //E...

I think the uuid option is the best. I tried to make relationships for the whole experiment to use uuid, but extra nodes are created and there is no relationship between the variety node (in this model I used only one variety) and parameters (Protein...

Thanks so much. I apologize for taking so much of your time as it's on me. In the first model, for each utilization of a compound, a new node must be created. I think the last model is what I need. Although it's not clear which uuid must be used (to ...
