Good morning, I'm actually facing the following problem:
I have 2.4 nm islands on a flat substrate. I would like to count them as precise as possible with Gwyddion. The procedure I'm following is to mark by threshold the islands and then in statistics check the number of grains. Unfortunately this number is not so precise, by hand i get 134 islands while with Gwyddion I get 294. The difference is too big. Moreover, if I change just a bit the threshold that number changes a lot. Instead, if I divide the projected area by pi times the square of the mean grain size (as if the grains were circles) I get a more reasonable number. Which method do you suggest? Thank you a lot Stefano ------------------------------------------------------------------------------ "Accelerate Dev Cycles with Automated Cross-Browser Testing - For FREE Instantly run your Selenium tests across 300+ browser/OS combos.
