gVCF size human genome
Hello all,
I got some gvcf using haplotypecaller in gvcf mode (-ERC GVCF). In input I am using human genomes, at around 35 / 40x. I wanted to know what is the classic size of such a gvcf? I ask that because I have a few between 17 and 21Go, but on the other hand another one is at 8.6Go. Haplotypecaller finished without generating any errors so I guess everything is okay but to be honest I don't know how to be sure it's okay.
Thanks in advance.

Using file sizes is not a reliable metric for most anything except making sure a tool worked i.e. it produced a non-zero byte file (of a reasonable size). VCF file sizes will depend on number of variants in your files and how compressible the files are.
Yes I'm agree, I did not know of any tools allowing to check the quality of my gvcf (or in any case if they are consistent).I finally used CollectVariantCallingMetrics and I get consistent snp numbers in the different samples.
