Data sets for a framework for variation discovery and genotyping using next-generation DNA sequencing data

Some of the BAM and VCF files are currently hosted by the NCBI:

ftp://ftp-trace.ncbi.nih.gov/1000genomes/ftp/technical/working/20101201_cg_NA12878/

• NA12878.hiseq.wgs.bwa.recal.bam -- BAM file for NA12878 HiSeq whole genome
  • NA12878.hiseq.wgs.bwa.raw.bam Raw reads (in BAM format, see below)
• NA12878.ga2.exome.maq.recal.bam -- BAM file for NA12878 GenomeAnalyzer II whole exome (hg18)
  • NA12878.ga2.exome.maq.raw.bam Raw reads (in BAM format, see below)
• NA12878.hiseq.wgs.vcf.gz -- SNP calls for NA12878 HiSeq whole genome (hg18)
• NA12878.ga2.exome.vcf.gz -- SNP calls for NA12878 GenomeAnalyzer II whole exome (hg18)

• BAM files for CEU + NA12878 whole genome (b36). These are the standard BAM files for the 1000 Genomes pilot CEU samples plus a 4x downsampled version of NA12878 from the pilot 2 data set, available in the DePristoNatGenet2011 directory of the GSA FTP Server
• SNP calls for CEU + NA12878 whole genome (b36) are available in the DePristoNatGenet2011 directory of the GSA FTP Server

• Crossbow comparison SNP calls are available in the DePristoNatGenet2011 directory of the GSA FTP Server as crossbow.filtered.vcf. The raw calls can be viewed by ignoring the FILTER field status

• whole_exome_agilent_designed_120.Homo_sapiens_assembly18.targets.interval_list -- targets used in the analysis of the exome capture data

Please note that we have not collected the indel calls for the paper, as these are only used for filtering SNPs near indels. If you want to call accurate indels, please use the new GATK indel caller in the Unified Genotyper.

Warnings

Both the GATK and the sequencing technologies have improved significantly since the analyses performed in this paper.

• If you are conducting a review today, we would recommend that the newest version of the GATK, which performs much better than the version described in the paper. Moreover, we would also recommend one use the newest version of Crossbow as well, in case they have improved things. The GATK calls for NA12878 from the paper (above) will give one a good idea what a good call set looks like whole-genome or whole-exome.
• The data sets used in the paper are no longer state-of-the-art. The WEx BAM is GAII data aligned with MAQ on hg18, but a state-of-the-art data set would use HiSeq and BWA on hg19. Even the 64x HiSeq WG data set is already more than one year old. For a better assess, we would recommend you use a newer data set for these samples, if you have the capacity to generate it. This applies less to the WG NA12878 data, which is pretty good, but the NA12878 WEx from the paper is nearly 2 years old now and notably worse than our most recent data sets.

Obviously, this was an annoyance for us as well, as it would have been nice to use a state-of-the-art data set for the WEx. But decided to freeze the data used for analysis to actually finish this paper.

How do I get the raw FASTQ file from a BAM?

If you want the raw, machine output for the data analyzed in the GATK framework paper, obtain the raw BAM files above and convert them from SAM to FASTQ using the Picard tool SamToFastq
