variables values not updating in workspace

Hi everyone. I've been working on a code and just lately realized this weird behaviour from the script. I was always measuring a diameter of a cropped image using imshow and ginput(2), today I changed to imtool, and I noticed that using imtool was actually changing the values of 'diameter' variable, while when using imshow it wasn't. Same thing happens with the cropped image ('Crop') size!

For example, if I run my code twice using imshow and ginput(2) I get:

1. First run: cropped image dimensions -> [200 100 3] and diameter -> 24
2. Second run: cropped image dimensions (this time with very different size on purpose) -> [200 100 3] and diameter (again different) -> 24

Later on I launch a GUI 'guiprova' in the script and while the updated results from 'guiprova' are stored in a m.mat file, their values are updated just when I run the script another time, so all the code after launching the GUI interface becomes inconsistent!

For example:

• Run the code, go to GUI interface and get the variables values -> variables values are stored before ending the GUI interface and are those from the previous code run

How can I solve these two problems? I know they are distinct but somehow both related to 'updating variable value' problems. I'll attach the code. Thanks!

It won't run for me because you forgot to attach m.mat.

I attached the GUI interface. The m.mat file would ideally be created in the GUI file and would save the variables to the workspace each time I run virtualnetcolori.m so I can do further operations with them. Instead, the virtualnetcolori.m goes on until the end not taking into account what I'm trying to do in the GUI (updating 4 variables). In the best case it returns me the m.mat file from the previous run.

To prevent this I even try to type delete('m.mat') in the OpeningFcn of the GUI so that the previously stored values that keep popping up are deleted everytime I run the code, but it's not working, it's like the virtualnetcolori.m reads all of that code before I can even input the mat file in the GUI interface. I can't find anything online for now.

What GUI? I see no fig file, just some m-files.

Attached that too now.

EDIT: I finally found something that suits my problem.

I'll test it a bit and come back if I have some issues.
