We have sequenced at the Broad Institute and released to the 1000 Genomes Project the following datasets for the three members of the CEU trio (NA12878, NA12891 and NA12892):
This is better data to work with than the original DePristo et al. BAMs files, so we recommend you download and analyze these files if you are looking for complete, large-scale data sets to evaluate the GATK or other tools.
Here's the rough library properties of the BAMs:
These data files can be downloaded from the 1000 Genomes DCC
Here are the datasets we used in the GATK paper cited below.
DePristo M, Banks E, Poplin R, Garimella K, Maguire J, Hartl C, Philippakis A, del Angel G, Rivas MA, Hanna M, McKenna A, Fennell T, Kernytsky A, Sivachenko A, Cibulskis K, Gabriel S, Altshuler D and Daly, M (2011). A framework for variation discovery and genotyping using next-generation DNA sequencing data. Nature Genetics. 43:491-498.
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/

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.
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 assessment, 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 we decided to freeze the data used for analysis to actually finish this paper.
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.
We have a problem: we have a truckload of material sitting around waiting to be published, but no time to actually write the papers. So we're looking for someone who will help us convert this computational biology goldmine into cold hard Nature Biotech/Methods papers.
This is a great opportunity for an early-career, postdoc-level scientist who has experience publishing papers, demonstrated writing ability, and is not afraid of wrangling complex technical material.
Make no mistake, we're not looking for a ghostwriter; this will involve intellectual contribution worth the authorship in high-profile publications. But the basic material is ready and waiting.
Here is the complete job description; feel free to ask questions in the comments or by private message to me (Geraldine):
Scientific Technical Writer
The Genome Sequencing and Analysis group seeks a scientist with excellent writing skills and experience with scientific publication to work with scientists and engineers on transforming notes and technical documentation for existing analytical methods and tools into polished papers aimed at high-profile journals such as Nature Biotechnology and Nature Genetics. In collaboration with researchers working at the forefront of bioinformatics, including the group that develops the gold-standard Genome Analysis Toolkit (GATK), the writer would be responsible for designing paper structure and identifying necessary content to (1) better explain the theory that underlies methods and tools and (2) powerfully illustrate use cases based on public datasets. The writer would focus their writing on the introduction, results, and discussion sections of the papers, expanding existing technical material, while the team will provide the methods sections.
The writer will be hired as a consultant, with a minimum of 20 hours/week of work (more hours are possible if desired).
