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.

NaN LOD in VQSR

Hi all, I'm running VariantRecalibrator on a SNP set (47 exomes) and I get this error:

##### ERROR ------------------------------------------------------------------------------------------
##### ERROR A USER ERROR has occurred (version 2.2-3-gde33222): 
##### ERROR The invalid arguments or inputs must be corrected before the GATK can proceed
##### ERROR Please do not post this error to the GATK forum
##### ERROR
##### ERROR See the documentation (rerun with -h) for this tool to view allowable command-line arguments.
##### ERROR Visit our website and forum for extensive documentation and answers to 
##### ERROR commonly asked questions http://www.broadinstitute.org/gatk
##### ERROR
##### ERROR MESSAGE: NaN LOD value assigned. Clustering with this few variants and these annotations is unsafe. Please consider raising the number of variants used to train the negative model (via --percentBadVariants 0.05, for example) or lowering the maximum number of Gaussians to use in the model (via --maxGaussians 4, for example)
##### ERROR ------------------------------------------------------------------------------------------

this is the command line:

    java -Djava.io.tmpdir=/lustre2/scratch/  -Xmx32g -jar /lustre1/tools/bin/GenomeAnalysisTK-2.2-3.jar \
    -T VariantRecalibrator \
    -R /lustre1/genomes/hg19/fa/hg19.fa \
    -input /lustre1/workspace/Ferrari/Carrera/Analysis/UG/bpd_ug.SNP.vcf \
    -resource:hapmap,VCF,known=false,training=true,truth=true,prior=15.0 /lustre1/genomes/hg19/annotation/hapmap_3.3.hg19.sites.vcf.gz \
    -resource:omni,VCF,known=false,training=true,truth=false,prior=12.0 /lustre1/genomes/hg19/annotation/1000G_omni2.5.hg19.sites.vcf.gz \
    -resource:dbsnp,VCF,known=true,training=false,truth=false,prior=6.0 /lustre1/genomes/hg19/annotation/dbSNP-137.chr.vcf -an QD \

    -an DP \
    -an QD \
    -an InbreedingCoeff \
    -mode SNP \
    -recalFile /lustre2/scratch/Carrera/Analysis2/snp.ug.recal.csv \
    -tranchesFile /lustre2/scratch/Carrera/Analysis2/snp.ug.tranches \
    -rscriptFile /lustre2/scratch/Carrera/Analysis2/snp.ug.plot.R \
    -U ALLOW_SEQ_DICT_INCOMPATIBILITY \
    --maxGaussians 6

I've already tried to decrease the --maxGaussians option to 4, I've also added --percentBad option (setting it up to 0.12, as for INDEL) but I still get the error.
I've added the option -debug to see what's happening, but apparently this has been removed from GATK-2.2.
Any help is appreciated...
thanks
