Hi all (and more specifically @ThomasBoudier)

I’d like to calculate surface area of a mosquito antenna, images taken as a confocal stack. I’m trying to use the 3D Convex Hull plugin to do this, but don’t understand the units of the results or if I’m even using it correctly.

My current workflow is:

Image>Stacks>3D Project

Analyze>3D Convex Hull>Measure All

Here is a link to an example image, and I’ve attached the results I’m getting from the workflow above.

Obtaining the surface area of the small projections is less important to me than calculating the surface area of the cylindrical core. Is this a the correct workflow to be able to measure surface area, and how do I convert these results to mm^2/mm^3?

Thanks so much,

Margo
