Did you remember to?

1. Search using the upper-right search box, e.g. using the error message.
2. Try the latest version of tools.
3. Include tool and Java versions.
4. Tell us whether you are following GATK Best Practices.
5. Include relevant details, e.g. platform, DNA- or RNA-Seq, WES (+capture kit) or WGS (PCR-free or PCR+), paired- or single-end, read length, expected average coverage, somatic data, etc.
6. For tool errors, include the error stacktrace as well as the exact command.
7. For format issues, include the result of running ValidateSamFile for BAMs or ValidateVariants for VCFs.
8. For weird results, include an illustrative example, e.g. attach IGV screenshots according to Article#5484.
9. For a seeming variant that is uncalled, include results of following Article#1235.

Did we ask for a bug report?

Then follow instructions in Article#1894.

Formatting tip!

Surround blocks of code, error messages and BAM/VCF snippets--especially content with hashes (#)--with lines with three backticks ( ``` ) each to make a code block.

Haplotype Caller -dcov flag

pauljpembertonpauljpemberton Member Posts: 6

Is there any way to override/re-implement the -dcov flag (which has been removed from the haplotype caller). I have a region that is almost 700 base pairs deep and continually causes a memory overload error. How can I restrict the coverage depth effectively?

    Hi Paul,

    What version are you using? The -dcov option is available in the current version, which is 2.6-4.

    I am using GATK v2.5-2, maybe it is just the online documentation that is missing the -dcov discription, but I was unable to discern whether or not -dcov refers to the number of reads starting at a single location (i.e. -dcov = 2 would only allow 2 reads to begin at the same place), or if it refers to the number of reads at any location (i.e. -dcov =2 would only allow 2 reads to appear at a specific location in the genome).

    Perfect, thanks for the quick responses!
