I'm trying to add data into my GUI, and use some of that data to populate a listbox.I have a function, FileRead that ingests a certain file, and returns a table with 10 fields. I've called that function and added it to the handle structure as below:

% add the tables into the handles structure
handles.OrigTable = FileRead('ntap_data.ntap');
handles.filteredTable = handles.OrigTable;
guidata(hObject,handles)

and then I tried to use that data in the CreateFcn for the listbox here:

function squawks_CreateFcn(hObject, eventdata, handles)
% Hint: listbox controls usually have a white background on Windows.
%       See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), get(0,'defaultUicontrolBackgroundColor'))
    set(hObject,'BackgroundColor','white');
end
squawks = categories(handles.OrigTable.Squawk);
set(handles.squawks,'String',squawks);
