Hi, I am running GATK on rice libraries and I get the following error with VariantRecalibrator. The command I use is:

java -jar GenomeAnalysisTK-2.8-1-g932cd3a/GenomeAnalysisTK.jar -T VariantRecalibrator -R genome.fasta -input chr5.vcf -mode SNP -recalFile chr5.raw.snps.recal -tranchesFile chr5.raw.snps.tranches -rscriptFile chr5.recal.plots.R -resource:dbSNP,known=true,training=true,truth=true,prior=6.0 all_chromosomes.vcf -an QD -an MQRankSum -an ReadPosRankSum -an FS -an MQ

This is how the program terminates:

I have read similar problems on GATK forums and based on those, it seems to me that the training set of VCFs is too small for my data. Is that so? If so, can you please tell me how can I fix it? This is for rice and I only have 1 set of known VCFs from dbSNP.

Can you also please confirm if my settings for 'known', 'training' and 'truth' are correct.

Thanks a lot in advance.

I'm trying to run GATK with the rice genome and I'm having trouble finding a known variant list of rice? Does anyone have a link or a more general list of known variant resources for other reference genomes?
Specifically, I found two rice genomes in dbSNP, but I can't find any documentation about which is which, and once I'm in the FTP site, which file I should be using?
ftp://ftp.ncbi.nih.gov/snp/organisms/rice_4530/
ftp://ftp.ncbi.nih.gov/snp/organisms/rice_4536/
Maybe take all the VCF files for each chromosome and cat them into one big file? Clearly, I'm a little clueless here :)
