Thibaut gives some technical elements to deal with duplicated spatial 
samples.  I agree with him but I think that if you want some help, we 
need to understand why you have duplicated samples and why you want to 
keep them. Your question is technical (it did not work!) but the choice 
of method is linked to the structure of your data, the related 
biological question..

Cheers,
