I have a loop which reads from a structure. The pattern might change in the loop. Sometimes I need to call the element that I want by this structure: 1) data.timepoints(6).cells{89, 1}{2, 1}{2, 1}(3) and sometimes this strucutre gives error: "Brace indexing is not supported for variables of this type." so that I have to change to the: 2) data.timepoints(6).cells{90, 1}{2, 1} (3)
Is there a way to add "if conditional": if you get error with the 1st arrangement do the second arrangement.

try
x = data.timepoints(6).cells{89, 1}{2, 1}{2, 1}(3);
catch ME
try
x = data.timepoints(6).cells{90, 1}{2, 1}(3);
catch MEME
%neither worked
end
end

Hello,
you can use a try-catch statement. However, I think it is better to add an if-condition that checks the cells.
