Warning when using "Read AML" operator

Whenever I use this operator to read some data set, I get the following warning message:

"DataRowFactory.string2Double(String): 'nan' is not a valid number!"

Could anyone help me out here on how this might be caused?

Hi,
yes I can. The String "nan" is simply not a number. It can't parse it, also "nan" probably stands for "Not a Number" a value of double variables used by rapidminer to encode missing values internally.

Greetings,
Sebastian
