overlay of X channels #257

Closed jovo closed 8 years ago

jovo commented 8 years ago

if we want to make a single image that sums over k channels, say, all 5 excitatory postsynaptic marker types, can we do that?

I think @willgray has some experience with this?

Hmmm - you mean in ndviz? Fairly trivial to do programmatically client side - guessing you mean server side as a dynamic render (or even on a request basis)?

If client side, lemme know.

@jovo not in ndstore maybe in ndviz.

jovo commented 8 years ago

i don't much care where. but, for example, if there are 6 excitatory channels in an AT dataset, i'd want to merge them all, and then only have to load 1 image (rather than 6).
i would do the same for the 6 inhibitory channels.

the reason is really speed, so i think i'd want it to happen on the backend, like i could make an ndviz project that has that property, and come back and look at it when it is ready.

@jovo I think this will now happen in ndviz because @alexbaden is working on this with OpenGL.

cool

jovo commented 8 years ago

shall we make a new "feature request" issue?

kunallillaney commented 8 years ago

@jovo Sure you can do so in Ndviz, since this is relevant there.
