Hi,  
I'm trying to see what are the inconsistencies on my data being inserted to database.  
The steps I do are:

1. create a myDb with the reasoning.schema.graphs=[http://ex.org/ontology](http://ex.org/ontology)
2. I add the ontology to that graph
3. I test consistency via command line: stardog reasoning consistency myDb
4. I add some triples to a different graph ([http://ex.org/data](http://ex.org/data))
5. I test consistency with the --named-graph parameter, and I get The database is NOT consistent.  
My question, is there a way to check what triples were inconsistent? I checked the stardog.log, but there is nothing there.  
Thanks in advance.

Hi, you can ask Stardog to explain the inconsistency for you via `stardog reasoning explain -i myDb`
