Hello,  
I am trying DELLY v0.8.2 for the first time, using ~x40 coverage data on a plant genome. The bam file was obtained by running bwa mem, then sorting and indexing the result.  
I am using default params for DELLY. My run results in a bcf file with no data (i.e. header is present, but no variants detected) and prints the following message to stdout:

    Sample:SRR1945819_map_to_pan.sort,ReadSize=51,Median=407,MAD=11,UniqueDiscordantPairs=230596

I find it very unlikely that there are no SVs between my sample and the reference, so I guess something is wrong with my data or the way I use DELLY.  
Any ideas on what might be going wrong?  
Thanks!
OK, this is a bit embarrassing, but turns out the problem was not with DELLY (or Manta), but rather with bcftools. Turns out I was using a very old version (0.1.19) that apparently can't read the new bcf. Once upgraded to 1.10.2, I am now able to read the output bcf, which is not empty at all.
