Please post the relevant part of the code only. The nature of the forum is a discussion in public. Therefore sharing the information by private emails is rarely useful.

I cannot find out, which is the line 1132. It is not useful to post such a huge code (without a proper formatting! Please read How to format code) and let the readers count lines to find the failing code.

I guess the problem is caused by something like this:

[rows columns] = size(Image);
Rimage = Image;
for y = 1:columns
  for x = 1:rows
    if (Rimage(x, y+1)==th1)

Now you try to process Rimage(x, y+1), when y=columns. Such an element does not exist, because Rimage does not have columns+1 columns.

You can use the debugger to check this. Type in the command window:

dbstop if error

Then run the code again until Matlab stops at the problem. Now check the values and sizes of the variables used in this line.

User posted the complete source in a different question. I cleaned it up and fixed some of the bugs and posted source at https://www.mathworks.com/matlabcentral/answers/396346-error-while-evaluationg-uicontrolm-callback#comment_559155
