Broken links in the gene view page for orthologs

[pcm32]

Orthologs links seem to be broken in the gene view page, for instance, coming from:

https://wwwdev.ebi.ac.uk/gxa/sc/experiments/E-HCAD-4/results/gene-info?geneId=ENSG00000142937&markerGeneK=44&k=44&colourBy=clusters

one faulty gene link would be:
https://wwwdev.ebi.ac.uk/gxa/genes/ENSCING00000006306

HTTP Status 404 – Not Found
Type Status Report

Message /gxa/genes/ENSCING00000006306

Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

Yes, that’s kind of expected. We’ve never had a great solution for orthologs. That means that the ortholog for chicken has no expression reported in our Gallus gallus datasets in bulk.

I remember that we decided to link to bulk by default because it’s where there’s a greater chance of finding ortholog genes, although I guess that a better alternative would be to link only if the gene is present in bulk-analytics (maybe we can create a similar collection of gene2experiment in bulk to speed this operation, but I’m not sure it’s worth for only a single operation).

Alternatively we could link to Ensembl, but we’d rather keep users in our service, of course. We should discuss this.

Yes, it is tricky, I agree that we want to keep users on our site. Maybe the web application receiving the user at the other side could have a descriptive message saying that there is no expression for that ortholog and offering an automatic redirect back to where they came from? Just an idea of course.

We’ll explore it in the next sprint. There should be some information or obvious message for the user.
