mwrite_bg cannot write zero? #15

Closed karl616 closed 8 years ago

Thanks for a nice tool!

I'm currently trying to merge multiple bigWig files into a single big table and thought mwrite_bg would be a good tools to use. In this case, the bigWig files sometimes cover different regions and it seems as if mwrite_bg introduces ones instead of zeros for uncovered regions.

wiggletools_x86_64_linux mwrite_bg - *.bw |grep -n -w "0.000000"

The above command identifies zeros on the first three columns, and nothing beyond that.

Is there something obvious I'm missing?

Best, Karl

This bug does reproduce with the last release binary, but magically disappeared in the latest version!

I updated the release binary, please re-download it and try again.
