VCF contrasts - workflow

AlmstrupAlmstrup Posts: 2Member

I am just starting with GATK but even though I have looked and looked I can not find a simple walkthrough of having many VCFs and running a range of contrasts based on sample data. I guess this must be one of the most common used tools.
I have 200 VCFs that I want to contrast in many different ways depending on sample phenotype.
Is there anyone that can direct me to a good guide on how to do that?
Thanks

    I am not sure I understand what you want to do, but it seems to me like you are talking about the Plink tools ? You can make queries in the GATK on vcfs using SelectVariants, VariantEval, GenotypeConcordance, CombineVariants and other tools.

    Well, lets say I want to group my vcfs in high and low BMI, high and low LDL etc. and look for the SNVs that differentiate the groups.

    That is definitely something you can do with VariantEval and GenotypeConcordance. Those tools have a lot of capabilities, you should look them up in the documentation.

    We don't currently provide a set workflow for this type of analysis because it there are so many possible variations depending on your study design.
