How to set limit of cell?

Dear all,

I have this part of code:

for i=1:numel(tmp)
  tmp2 = shape.spine{i};
    if numel(tmp2)>2
    cnt=cnt+1;
    t=[t i];

plot(tmp2(:,2),tmp2(:,1), 'o-y')
end
legend('Okolí hrudníku', 'Páteř + žebra');
end
tmp = tmp2;

and after this for loop there is this error:

Index exceeds matrix dimensions.

Error in DP_segment_final>Pater_Callback (line 456)
  tmp2 = shape.spine{i};

I think, that there is problem in struct shape in cell spine, but I don´t know, how to extend or set limits of this cell. Or exist some other solutions for my problem?

Thank you for your answers.

If you want to create a loop over the existing elements of a cell, use the number of elements of this cell as upper limit:

for i = 1:numel(shape.spine)
  tmp2 = shape.spine{i};
