Thanks for letting us know. We’re looking into this and hope to have an update for you soon.

Thanks for your patience. An error occurred with the create a feature region tool that prevented annotations from being useable. We’ve corrected the impacted images manually.

In the near future we hope to bring MiewID into Manta Matcher to prevent this type of issue and simplify the matching process for mantas.


Hi, we are still having issues when trying to run the Manta Matcher. After creating the Optional Feature Region, it displayed the attached screenshot with no option to run matching.

It’s because the Taxonomy is missing from the attributes section:

MantaMatcher can’t start matches if it doesn’t know which species to look for. Click the Edit button to update and save the taxonomy, refresh the page, and you should see the option to start a match.

It looks like your 6 most recent uploads are missing the taxonomy, so fixing this should unblock you.

Ah I missed that, thanks for your help!
