regions.dist.txt = global.dist.txt  when running mosdepth -n -b 10000 -t 4 -F 2816 
I think i understand from another closed issue (#18) that you expect that global.dist.txt will always be "per base", but why make 2 identical files?  Perhaps when passing a bed file to limit to certain regions this makes more sense...

Am I missing something here?
