problem with calculating smallworldness

Hi! I am currently having difficulty when I ask GraphVar to calculate smallworldness using random networks. It seems to run well until the final step of exporting the variables; then, I get the following error: Index exceeds matrix dimensions. Error in GraphVar_CalcExport_Callback (line 66) if(sum(size(Result{1}) > 1)) Error in gui_mainfcn (line 95) feval(varargin{:}); Error in GraphVar (line 40) gui_mainfcn(gui_State, varargin{:}); Error in @(hObject,eventdata)GraphVar('GraphVar_CalcExport_Callback',hObject,eventdata,guidata(hObject)) Error while evaluating uicontrol Callback Do you have any thoughts about what I might be doing wrong? Thank you! Chelsea
