Sharkbook - spot mapping (modified groth + i3s) performance

Hi, in Sharkbook we still have to rely heavily on the Modified Groth and i3S algorithms to identify sharks.

Recently however, spot maps are rarely coming back with more than 5 potential matches (it normally returns around 50 matches).

Could you double check if its working properly?

Here are some examples:

Thanks

I just re-uploaded a shark encounter and did a spot map to demonstrate the issue.

In the previous spot map, it produced a number of results.
In the new spot map, no results came up for either Modified Groth or i3S:

Check the spot map results for these two encounters:

Hi @Sarah_Aus_SpotaShark

Let me see what I can find out for you.

Thanks for your patience! Thankfully, this wasn’t a bug. We re-ran both links and the one with the missing spot map shows results and that 6930 patterns were considered. The other links results also look good and I also had Jason verify that it’s normal.

If you see questionable spot map matches again, try waiting a little bit and then re-running the match in case the questionable result was a hiccup in the identification process.
