Invalid END position

[ACEnglish]

Using sniffles 2.4 in merge mode on chm13 produced an invalid variant.

This isn't a huge problem because most vcf parsers can handle the error plus SVs at the beginning of chromosomes should be a rare occurrence(?). But I just wanted to report it.

Error:
[W::vcf_parse_info] INFO/END=0 is smaller than POS at chr11:1

Hi @ACEnglish,

Which dataset did you see this on?

Thanks,
Hermann

This was in the 1kgp ONT data. Fritz has the snf files locally. https://www.biorxiv.org/content/10.1101/2024.04.18.590093v1.full.pdf

@hermannromanek it looks like Sniffles is diminishing by 1 the end when outputting the END position and for INS its the same as start that when is 1 it becomes zero
