DNase tagcounts in bigwig format, can be directly viewed in genome browser.

fwd.bw: DNase tagcounts on the forward strand.
rev.bw: DNase tagcounts on the reverse strand.

Note: the bigwig format is 1-based, similar to wiggle (wig) format. From UCSC: "Chromosome positions are specified as 1-relative. For a chromosome of length N, the first position is 1 and the last position is N."
