Comment(by rspringuel):

 Shoot, for got to use code blocks above.  This only really affects the
 patch-over code so I'll just repost that:


 {{{
 def nanunique(x):
     a = numpy.unique(x)
     r = []
     for i in a:
         if i in r or (numpy.isnan(i) and numpy.any(numpy.isnan(r))):
             continue
         else:
             r.append(i)
     return numpy.array(r)
 }}}
