Thank you for your help!
So its not usually from excel sheets, I just listed that in case there was excel markup leftover ..like \r returns or something.
Question though....I don't understand how I then access the information following your method. For example, if I wanted the probability of a AAC to AAA (.0011) how do I get to that value? You've created an array where each cell has the ref to a hash....which in turn holds the key value pairs of each row with respect to that column... correct? How do I access the info for individual cases?
