How to solve problem with NumSeries error in mvregress function?

I tried to do longitudinal analysis using mvregress function, and I follow the instruction on mathwork at https://uk.mathworks.com/help/stats/longitudinal-analysis.html#d120e51334, however when I try to run this part I get this error

Error using statcheckmvnr (line 42)

Invalid number of series in cell array elements (should be NumSeries).

Error in mvregress (line 251)

statcheckmvnr(Data, Design, Param0, Covar0, isequal(EstMethod,3));

Error in geneExpression_ranova (line 32)

[b,sig,E,V,loglikF] = mvregress(X,Y);

my data is like this:

The matrix Y contains response data for 4 mice. The response is the fold change measured at 7 time points. Each row of Ycorresponds to a mouse (a total of four mice), and each column corresponds to a time point. The first two subjects are sham, and the second two subjects are treated mice.

Y = receptor_Name;

 figure()
 t = [3,6,9,12,15,18,21];
 plot(t,Y)
 hold on
 hf = plot(t,Y(1:2,:),'^');
hm = plot(t,Y(3:4,:),'o');
legend([hf(1),hm(1)],'sham','treated','Location','NorthEast')

title('Longitudinal Response')
ylabel('Fold Change')
xlabel('Time')
hold off
 
 
X1 = Y(1:2,:);
X2 = Y(3:4,:);

X = cell(2,1);
X(1:2) = {X1};
X(3:4) = {X2};

[b,sig,E,V,loglikF] = mvregress(X,Y);
[b sqrt(diag(V))]

Can you upload your data in a MAT file (using the paper clip icon), so we can run exactly what you are running?

yes here is the mat file

thanks
