Error in UIControl Callback with unrecognised variable

Hi, the error message I keep getting is Error using UIadjusted>borient_callback

Connectivity list refers to a point index that exceeds the number of points in coord.

'coord' is not being recognised as a variable which may be the issue. It is defined in an external function which is called on in the main script (UIadjusted) but maybe there is a problem with it being passed between the scripts. I don't know how to correct or visualise the problem. I don't have a ton of coding experience so any help or suggestions are welcome!

Can you share the code so we can try to see where the problem is ?

UIadjusted is the main script. I think the error is specifically from line 228. dp_lr_orientation is one of the functions called on through PCOrientation which is the main orientation function however, coord is first defined in dp_lr_orientation.

Here are lines 421-423 in UIadjusted.m, which are inside the function borient_callback. Line 422 is the line that throws the error (because that's what line 422 is intended for).

if max(ConL(:)) > size(coord, 1)
    error('Connectivity list refers to a point index that exceeds the number of points in coord.');
end

As you can see, the error happens when max(ConL(:)) > size(coord, 1) and has nothing to do with coord not being recognized.

"[coord] is defined in an external function"

It is true that a variable called coord is calculated in the function dp_lr_orientation, here (lines 84-87):

xcoord = origin(ptc.Location(:,1));                                %extracts coordinates from new point cloud and stores 
ycoord = origin(ptc.Location(:,2));                                %coordinate arrays and matrix            
zcoord = origin(ptc.Location(:,3));
coord=[xcoord,ycoord,zcoord];

However, that variable coord is not the same as the variable coord in the function borient_callback, and in fact the variable coord in dp_lr_orientation is entirely unused. (You might notice an orange squiggly underline underneath coord in the editor and when you hover over it a message appears that says "The value assigned to the variable 'coord' might be unused.")

The variable coord in borient_callback is calculated from the xcoord, ycoord, and zcoord that are returned from the function PCOrientation, here (lines 385-386 of UIadjusted.m):

[xcoord,ycoord,zcoord,ptc,De,Pe,siding,scatterRatio]=PCOrientation(oc);     %calls on PCOrientation to orientate the model correctly
coord=[xcoord,ycoord,zcoord];                                               %creates coordinate array from seperate coordinates from the point cloud

Maybe the variables xcoord, ycoord, and zcoord returned from PCOrientation are the same as the ones returned from dp_lr_orientation - I don't know because I don't have PCOrientation. Without all the necessary functions and data, no one but you can run the code.
