Problems with Convex Hull in STACKS


Hi everybody,
is anyone getting problems with measuring Convex Hull of particles in image stacks?

I developed a macro for analyzing the shape of particles in stacks, but I experienced some difficulties with the convex hull: the macro tends to calculate the correct value of convex hull for the first image but it shows difficulties to re-draw the convex hull to the following particles in the stack. Is anyone experienced this kind of problem yet?

Many thanks to anyone who wants help me,



I am not familiar with this procedure but I am guessing whomever does try to help you is going to need a copy of your macro and a test image. If you can provide them.
