LUMPY SV call without quality score

I am using LUMPY to call structure variation, but the problem is all the quality score returned by LUMPY is marked as '.'

Is it due to low sequencing depth?

or may be there is just no QUAL... why would it be a "problem" ?

I checked the other people's post, they have it and all the REF column are shown as N..

I've got some lump-sv (lumpy express) in my server: there is no QUAL.

But the other problem I have is the REF column are all N, although it tells me it is DEL or INDEL or something else..

again, why do you need this information. Imagine you have a deletion of 1 megabase; unless you're using a symbolic allele, it would need a VCF file with a REF allele of 1E6 characters....

Thanks for your explanation. I have read the VCF format description, I thought it will tell me the details of the changes..
