hmdb edges pointing the wrong direction

[cbizon]

Match (c:biolink:PhenotypicFeature {id:"HP:0002017"})-[a]-(x)-[b]-(d:biolink:ChemicalEntity {id:"PUBCHEM.COMPOUND:3776"}) return *

Shows a number of cases where x is a gene and there is an edge saying that the gene affects the abundance of d (the chemical). The edge is coming from HMDB.

This is almost certainly turned around the wrong way.

I'm not sure that this is related. And looking back at this ticket, I'm not sure why I was convinced that the abundance edge was pointed the wrong direction. It could go either way, really. But I think we need to review the chemical/gene directions in HMDB overall.

These edges are pointed in the other direction now. We did previously switch the direction of the affects_abundance_of edges too though, so we should double check that was correct.

For the affects_abundance_of edges I agree with Chris's above comment, it could go both ways. I am not sure how we would clarify which way the specific edge is pointing.

I think it's a question of going back to HMDB and reviewing whatever documentation they have about what their tables mean, and making sure that it's consistent with how we represent the dat.
