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.

Custom Walker :

Hi all,

I'm playing with the GATK3.6 API, writing a custom walker.

@DocumentedGATKFeature(
        summary="Annotate Variants with eigen data",
        groupName = HelpConstants.DOCS_CAT_VARMANIP,
        extraDocs = {CommandLineGATK.class}
        )
public class EigenVariants extends AbstractVariantProcessor {
public abstract class AbstractVariantProcessor
extends RodWalker<Long, Long> implements TreeReducible<Long>
{
    @Input(fullName="variant", shortName = "V", doc="Input VCF file", required=true)
    protected RodBinding<VariantContext> variants;

    @Output(doc="File to which variants should be written")
    protected VariantContextWriter writer = null;
(...)

I'm compiling, packaging & everything is fine:

$  java -cp GenomeAnalysisTK.jar:mygatk.jar org.broadinstitute.gatk.engine.CommandLineGATK -T EigenVariants --help
(...)
Arguments for EigenVariants:
 -eigen,--eigenDirectory <eigenDirectory>   The Eigen directory
 -V,--variant <variant>                     Input VCF file
 -o,--out <out>                             File to which variants should be written
(...)

but when I only add one import from my source (no variable, only the import):

import com.github.lindenb.jvarkit.tools.vcfeigen.EigenInfoAnnotator;

then the PluginManager goes mad:

$  java -cp GenomeAnalysisTK.jar:mygatk.jar org.broadinstitute.gatk.engine.CommandLineGATK -T EigenVariants --help
