I wanted to play with and integrate gene copy number data provided by the Broad Institute and available at : http://www.broadinstitute.org/ccle/data/browseData?conversationPropagation=begin
But when I had a look to the section DNA Copy Number and did download the set CCLEcopynumberbyGene_2010-10-28.txt.gz I did not get the data I was expecting.
Indeed I was expecting integer values like it is provided in the file TCNcelllines_120310.xls by the Sanger Institute.
So if someone could have a look at it and explain me why it is not integer values that are provided. And actually the values are strange to me because I don't understand their meaning.
I am eager to learn the piece information I have missed.
Below is the screen-shot of the file (Larry thanks for the suggestion):
