Error in CountCovariates as well in BaseRecalibrator
I am using the latest version of GATK, During the Quality score recalibration I found the following error.
The code was as follows: java -Xmx4g -jar GenomeAnalysisTK.jar -l INFO -R ~/SCZ_data/ref_hg19/hg19sum_upper.fa --DBSNP dbsnp132.txt -I ../output.marked.realigned.fixed.bam -T CountCovariates -cov ReadGroupCovariate -cov QualityScoreCovariate -cov CycleCovariate -cov DinucCovariate -recalFile input.recal_data.csv
ERROR MESSAGE: Could not find walker with name: CountCovariates
later i understood that i should use BaseRecalibrator for this new version of GATK, but i am still not sure what to put in the reference file for SNPs with the -knownSites command from where to obtain these vcf files?
java -Xmx4g -jar GenomeAnalysisTK.jar \
-T BaseRecalibrator \
-I my_reads.bam \
-R resources/Homo_sapiens_assembly18.fasta \
-knownSites bundle/hg18/dbsnp_132.hg18.vcf \
-knownSites another/optional/setOfSitesToMask.vcf \
Can you please suggest me what should be done??
