I have a 1x3001 cell, 'y', and I want matlab to loop through all the cells and save all the rows where the value in column 2 is <-0.13.

I have the following code but i get the error below. Please could somebody help me fix this?

%for all the csv files (3001)
for b = 1:length(data)
    %get the ID number (:,1) and coordinates (:,6) and save them in an array
    y{b} = table2array(data{b}(:,[1 6]));
    %find and save all the rows in each csv file where column 2 is <-0.13
    g{b} = y{b}(y(:,2) <= -0.13, :);
end 
Undefined operator '<=' for input arguments of type 'cell'.
