how to skip an error inside a loop?

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.
