Weka output of attribute selection

I'm using weka to select attributes from my dataset, but I don't understand one thing: for example, I have this output after attributes selection with InfoGainAttributeEval + Ranker

Ranked attributes:
 0.354       1 attr12
 0.333      46 attr4
 0.316      75 attr7
 0.304      96 attr1

Well, I know the first value is the information gain, but what does it means "1 attr12"? What's that number "1"? Thanks

Solved! "1 attr12" is the first attribute, named "attr12". So, the "1" is the index of the attribute.. 46 is the index of the attribute "attr4", and so on..
