Hi Diego, The reason you are seeing high numbers for the pValue is because we use -log10. More information about ENCODE file formats can be found here:
http://genome.ucsc.edu/FAQ/FAQformat.html and additional information can be found by clicking on the "schema" links for each track in the track description pages. Hope that clarifies the issue for you. If you have further questions, please email the list: [email protected].

How do they are calculated? I never saw something like that before. I usually think about pValues as quantities in the range from 0 to 1. So those values confuse me a little bit. On the other hand, how useful are your score fields for statistical purposes? I understand the primary use of those fields is for the graphics. However, it seems they are "normalized" data, so I'm wondering whether I can use them saving me to reinvent the wheel.
