I'm creating a big arff format dataset (40K attributes). The original values are in scientific format, (i.e 0.526e-08), but I've read that Weka doesn't handle this format. So I converted each values using a precision of 15 digits, i.e 0.526e-08 becomes 0.000000005260000. Now when I open the dataset with Weka, the information for each attributes (minimum, maximum, std, mean) are equal to 0. The attributes are defined as numeric. It seems that Weka doesn't recognize properly the values but it consider them all as 0. What's wrong? Is the values of the attributes too small?
