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!


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

Unified Genotyper quality call

Hi,

I am running the unified genotyper in "EMIT_ALL_CONFIDENT_SITES" with the latest version of GATK and am getting some odd quality assignments of 10000030. It is clear that these sites are not very stellar, so I am wondering what is happening to these sites. Any thoughts?

Below is a snippet from one such region, starting with some seemingly "normal" rows and ending with this seemingly odd assessment of quality. Any thoughts? As some background info, this sample is quite different than reference, so not abnormal to have lots of missing regions when aligned against the reference that I used. It is bacterial. Here is the command line that I ran:

GenomeAnalysisTK.jar -T UnifiedGenotyper -dt NONE -I "$i" -R ../../Ref.fasta -baq RECALCULATE -nt 4 -ploidy 1 -out_mode EMIT_ALL_CONFIDENT_SITES -o "$j".vcf -stand_call_conf 100 -stand_emit_conf 100 -mbq 20
