Hi,

When I try to run the bigWigToWig utility, it seems to output results
in BedGraph format rather than Wiggle format. For example, I
downloaded one of the ENCODE ChIP-Seq signal files,
wgEncodeOpenChromChipMcf7CmycVehSig.bigWig. When I try to convert it
into wig format, however, I get BedGraph output:

$ bigWigToWig -chrom=chr22 wgEncodeOpenChromChipMcf7CmycVehSig.bigWig chr22.wig
$ head chr22.wig
#bedGraph section chr22:16050039-16055390
chr22   16050039        16050339        0
chr22   16050339        16050387        0.0001
chr22   16050387        16050413        0.0002
chr22   16050413        16050432        0.0003
chr22   16050432        16050448        0.0004
chr22   16050448        16050461        0.0005
chr22   16050461        16050474        0.00006
chr22   16050474        16050485        0.0007
chr22   16050485        16050496        0.0008

I get the same behavior with the current linux 64 bit binary version
of the utility available for download, as well as with a version that
I compiled from the Kent utility source tree.

I feel like I'm probably missing something terribly obvious, but I've
searched the archives and other related sites and can't seem to figure
out what's going on. Is the tool supposed to behave this way?

Thanks in advance,

Chris
