I have been trying to start exploring the Reactome Graph Database today following the instructions given at https://reactome.org/dev/graph-database#GetStarted
I have installed Neo4j Desktop 2 (version 2.0.5)
I have installed Java Runtime Environment v.25
MacOS version 26.1
I have downloaded from Reactome the file:
reactome.graphdb.dump
I have also a folder:
graph.db
In Neo4j Desktop, I have created an instance called ‘Reactome', and opened/imported the database from the dump-file.
In a newly created Neo4j data folder, I have located the file ’neo4j.conf’ and added the following lines there:
dbms.default_database=reactome.graphdb
dbms.recovery.fail_on_missing_files=false
unsupported.dbms.tx_log.fail_on_corrupted_log_files=false
I have made sure that both the dump-file and the folder graph.db are in the subfolder 'path/to/neo4j/data/databases/'
When I try to explore the Reactome Graph Database in Neo4j Desktop App, I get the following error:
Please reload the application, if the problem persist please contact Neo4j Support. Error: {"type":"ERROR.NODATABASEACCESS”}
I have also tried the Web Browser (Safari) by going to the link:
http://localhost:7474/browser/
The Reactome.graphdb seems to have been recognized as judged from the top bar of the page, where I can also see the version of Cypher (v.5):
Here is the screenshot of the upper half of the browser page, where the error can be seen too when trying to run a Cypher query:
I am writing to you because essentially I am not sure what else I can try, and therefore heavily relying on your support.
Any input would be appreciated.
