Selecting options for saving array

I want to save a 375x5 array as .txt file. Everything is fine so far until I make a selection via my GUI and some radiobuttons which colums to save. I wrote a script but noticed later on, that it's not possible to select only the last 2 colums because in this case the last colums move forward so they doesn't exist anymore when the code comes to their selection.

Any suggestions how I can change my if- or for-cases to change the problem? Thank you

My code:

 calc_diameter = alldia;

            if status_diameter(1,1) == 0;
                calc_diameter(:,1) = [];
            elseif status_diameter(1,1) == 1

            end

             if status_diameter(2,1) == 0;
                calc_diameter(:,2) = [];
            elseif status_diameter(2,1) == 1

             end

              if status_diameter(3,1) == 0;
                calc_diameter(:,3) = [];
            elseif status_diameter(3,1) == 1

              end

               if status_diameter(4,1) == 0;
                calc_diameter(:,4) = [];
            elseif status_diameter(4,1) == 1

            end

        FinalDia = mean(calc_diameter,2);
        StDevDia = std(calc_diameter,1,2);

        dlmwrite(SaveName,[xscale calc_diameter],'delimiter','\t');        

        dlmwrite(SaveName,[xscale FinalDia StDevDia],'delimiter','\t');

Hi,

how about cutting out the data you want to save? You have 5 radio buttons and you can figure out which one is checked. So you can built up an array like this [0 0 0 1 1] where 1 stands for radio button is checked. Once you have that array you can easily do:

selection = logical([0 0 0 1 1]);
alldia = rand(375,5 );
calc_diameter = data(:,selection);
