Origin Version : 7.5 SR2
Operating System: Win XP
These three things are playing on my mind.
Is it possible to perform particle counts on 2D images in origin? The peak count function doesn't seem to be up to this task.
Is it possible to record a macro-style instruction set so that I don't have to keep doing the same process over and over again?
Has anyone written a script for calculation of the second-order moment (i.e. integral x^2 f(x) / integral f(x)) from a graph?
Thanks.

Hi,
Just supplimenting Mike's post...
You can set the image matrix cell values to extract paticles by doing the menu: e.g.,
Matrix:Set Values: Cell(i,j) = cell(i,j)>500?1:0
Then, for example, you can add (or integrate) all cell values and devide by the average particle size.

Hi RobWL,
It's not possible to record GUI actions but everything you can do by GUI can also be performed in LabTalk and Origin C.
...This add-on will integrate a chosen region of an image. There is probably a simple relationship between integral and particle count.
