Reciprocal transclocations

[cv55]

Hello, thanks for the great tool.

After running Gridss and Gripss for filtering I end up with ~20 BND events in my Vcf file. I noticed that every event has two lines in the Vcf file corresponding to the breakends at the two invlolved chromosomes. Here is an example:

Is it safe to assume that all these BND events are reciprocal?

Thanks a lot.
