Test-drive the GATK tools and Best Practices pipelines on Terra

Check out this blog post to learn how you can get started with GATK and try out the pipelines in preconfigured workspaces (with a user-friendly interface!) without having to install anything.

No reference genome (de novo SNP calling)

sstwins21sstwins21 New ZealandMember

Hi GATK team,

I am new to bioinformatics and could you help me with this problem?

I am trying to call SNPs on my polyploid samples, consisting of diploids and triplods. But I used a reference genome from a relative species that is a diploid.
For this reason, I think all my SNPs only show diploid alleles even for the triploid samples.
Thus I want to create my own reference genome by assembling the representative samples (mix of trploids and diploids) like shown in the GATK slide.

I have done mapping before using bwa or bowtie, but I do not know how to assemble using my own samples...
This may not be the GATK problem, but could you help me how I can assemble my own reference genome please?
Thank you.

Kind regards,
