I have loaded the data using SciGraph and moved the database folder to a Neo4j server 3.xx.
(migrating to 4.0 wasn't successful)
I am able to work with the graph but I am missing the index created.
I can see data stored in index store
:sysinfo
but nothing when I do
CALL db.indexes
Any suggestions?

for running scigraph output in neo4j you need to move the data out of the graph folder into a /databases/graph.db directory, for example
mv graph/* /some/path/databases/graph.db/

then in your neo4j.conf
dbms.directories.data=/some/path

I didn't have any problem loading the database folder. The issue is missing index.

I did some pizza tests, loading the database and upgrading it from 3.4.7 (current scigraph version) to 3.5.x data and index looks okay there.
In pizza example, when I CALL db.indexes, I can see "INDEX ON :food(label)"
provider: { "version": "2.0", "key": "lucene+native"}

In my graph, I can't see that index, but I see data usage in Index Store.
