Matlab error: GROUP must be a cell array or matrix of grouping variables with the same length as Y

This is the error I received:

Error using maineffectsplot (line 99)
GROUP must be a cell array or matrix of grouping variables with the same length as Y.

This is my code:

%% main effect plot

data = [0.9000    1.0000    1.0000;    1.1000    1.1000    1.2000;    1.2000    1.1000    1.1000;    1.4000    1.4000    1.4000;
    1.0000    1.0000    0.9000;    1.1000    1.2000    1.1000;    0.9000    0.8000    0.8000;    0.9000    1.0000    0.9000;
    0.7000    0.8000    0.7000;    1.1000    1.2000    1.2000;    1.1000    1.0000    1.1000;    1.1000    1.1000    0.9000;
    0.8000    0.8000    0.7000;    0.9000    1.1000    1.0000;    0.8000    0.9000    0.8000;    1.1000    1.1000    1.0000];

    data = data';

    g1 = {'(1)', 'A', 'B' ,'C', 'D', 'AB', 'AC', 'AD', 'BC', 'BD', 'CD', 'ABC', 'BCD', 'ABD', 'ACD', 'ABCD'};
maineffectsplot(data, g1)

The help maineffectsplot says "Each grouping variable must have the same number of rows as Y" Y has 16 rows, g1 has 16 rows as well, I don't understand why do I receive this error

I tried different combination of data, g1 ; data, g1' etc none of these work

This picture confirmed that I somehow managed to have them both have 16 rows

Thank you!

You only need one cell in g1, but it has to contain 16 rows. Try using

g1 = {['(1)';'A';...;'ABCD']}
