GUI "Cell contents reference from a non-cell array object" error

[econo...@appstate.edu]

Hello I am trying to create an EBSD GUI.

In the GUI one of the options I am working on would remove Dauphine twin boundaries from the EBSD. The code I am using to remove the twin boundaries works fine in a script but when I plug it into the GUI I get an error.

This is the code I am using to remove the twin boundaries:

% Find all quartz-quartz grain boundaries

gb_qtz = grains.boundary('Quartz-new','Quartz-new');

% Find all boundaries with rotations of 60+/-5 degrees around the c-axis - these are Dauphine twins

rot = rotation('axis',Miller(0,0,0,1,CS{2}),'angle',60*degree);

ind = angle(gb_qtz.misorientation,rot)<5*degree; 

twinBoundary = gb_qtz(ind);

% Merge grains separated by twin boundaries 

[mergedGrains,grains.prop.parentId] = merge(grains,twinBoundary);

Error I am receiving:

Cell contents reference from a non-cell array object.

Error in GUIwow>calc_Callback (line 291)

rot = rotation('axis',Miller(0,0,0,1,CS{2}),'angle',60*degree);

I feel the error has to be GUI related since the code works fine in a separate script. Does anyone know what the issue may be?
