hi:

I read a text file that gives me a list.
nLevel[8, 10] = Import["output8_10.txt", "List"]

{-10,-9,-7,-3,1,3,3,17}

I have no problems calculating mean, variance etc. with the list.

When I use:

Select[nLevel[8,10], #<0]

yields

{}

despite negative elements.

I cannot figure out why.

Thanks,
