Pyr Challenge 2: Mossy Fibers!

Would you be okay with me adding this image to the blog post as an example? I will credit you.

Sure thing!

Is it possible, that an MF just ends inside our dataset?

Yes! They can indeed just end here in CA3.

If a segment is an MF, but doesn’t need any further proofread, what should I set in the “Proofread?” column?

Just mark it as “Yes”, but no need to paste any segment IDs since it hasn’t changed.

Is anyone else really struggling not to autocomplete the acronym much more rudely every time they type in “MF” for it being a Mossy Fiber? xD

And if you weren’t before and are now… I’m sorry >.>

From the first time I’ve seen the acronym, I always think about Samuel L. Jackson xD

is this considered too small?


lower end of branch ends at dataset, the others nub out pre-dataset end.

No, that’s big enough. It’s when it’s just the bouton and tiny little twig right on the edge that we consider “too small”.

ok, gotcha, thnx.

If we find a mossy fiber that’s not part of the challenge list, do you want us to tack it on at the bottom or discard it?

Wasn’t a merger, just a mis-click that traced out to an MF.

Just discard it. Feel free to proofread it if you’d like (save someone in the future). But it’s highly likely it’s already on our list of Potential MFs.

This list is just 2k out of 58,506 potential MFs btw!
Hence our part 1 on the Challenge tab :wink: makes things more manageable.
We’re all part of multi-pronged approach to ensuring we get all these MFs!

Great to hear, that there’s so much more! I really like them (unlike the, sometimes, big mergers with several segments, lol).

they are both connecting with thorny cells, but not really looking like the mossy cells i have seen so far

not an MF (from the gsheet) but daaaaaauuuumn this was too nice a cell not to proofread lol

it is indeed, imo.
