[galaxy-dev] Local data for encode tools

Hi all, I want to use the encode tools as "random intervals" in my local instance of galaxy cistrome. I have the xml file and the py file which can run the tool, but it required any local data. These data are referenced in tool-data/regions.loc but I've not found where can I procure the bed which are referenced in this file. Have you any idea to find them or to build them ? Or just any example of their format, may be I can reproduce them with other data. And for the future, is there a precise web page for admin which references all ways to transfer useful local data? Thanks a lot. Julie
