support for haploid/different ploidy

[alexweisberg]

Hi,

I am really interested in using graphtyper for my bacterial genome SNP calling as there is a lot of diversity in some lineages and typical SNP calling pipelines run into issues when strains are fairly diverged from a reference. I was able to run graphtyper on a bacterial genome dataset, and manual inspection of the output shows several heterozygous variant calls (0/1) which are incorrect with a haploid genome. I was wondering if there is an option to set the ploidy level for SNP calls? Thanks!

Best, Alex

Hello, thanks for posting. It is currently not possible to set the ploidy level but we will likely add the option of haploid in the future. For now, I would suggest filtering the heterozygous sites.

All the best, Hannes
