nblast: Visualizing a specific hit in the 3D plot

[Erginkayam]

After NBLASTing, we currently don't have the option to only visualize a specific hit (e.g. the 8th hit) together with the NBLASTed neuron in the 3D viewer. Currently we can use the "hits=n" argument to narrow it down to the top n neurons, it would be useful to have the option to be able to show only the nth hit instead.

This seems like a good idea. The equivalent function in elmr assumes that hits is a vector (e.g. 1:10)

Of course you can always fine tune your searches using R – happy to help setup if you want.

That's a fairly straight forward addition. And just like @jefferis said: catbot simple turns a hits=5 into an R vector 1:5. Syntax for single hit could be e.g. @catbot nblast #12345 hits=[4] or, for two specific hits @catbot nblast #12345 hits=[3,4]
