MATLAB: How to find unique values in a field of a nested struct

MATLABunique

Hi,
I have a nested struct user.data (attached) anda I want to find the unique values of the field touristicRoute (user.data.touristicRoute)
I have tried this code:
for m=1:size(Cluster_USERS,1)
    for i=1:size(userTouristicTraj(m).touristicData,2)
        if (user(m).data(i).touristicRoute~=0)
            uniqueValues=unique(user(m).data(i).touristicRoute)
        end
    end
end
but it doesn't give me the right value, can you help me?

load matlab.mat
N = length(user) ;
iwant = cell(N,1) ;
for i = 1:N
    M = length(user(i).data) ;
    val = cell(M,1) ;
    for j = 1:M
        val{j} = user(i).data(j).touristicRoute ;
    end
    val = cell2mat(val) ;
    iwant{i} = unique(val) ;
end
