-- Multi-allelic variants are split into their bi-allelic version, trimmed, and we attempt to provide a meaningful genotype for NA12878 here. It's not perfect and needs some discussion on how to handle het/alt variants
-- Adding splitInBiallelic funtion to VariantContextUtils as well as extensive unit tests that also indirectly test reverseTrimAlleles (which worked perfectly FYI)
-- MongoVariantContexts and MongoGenotype have a validate() function that ensures that the information is consistent, in anticipation of potential problems with the data coming in from reviews via IGV
-- Divide the world into production, development, and test DB, via the NA12878DBArgumentCollection
-- Idea is simply to create a persistent database of all TP/FP sites on chr20 in NA12878. Individual callsets can be imported, and a consensus algorithm is run over all callsets in the database to create a consensus collection, which can be used to assess NA12878 callsets for GATK and methods development
-- Framework for representing simple VariantContexts and Genotypes in MongoDB, querying for records, and iterating over them in the GATK
-- Not hooked up to Tribble, but could be done reasonably easily now (future TODO)
-- Tools to import callsets, create consensus callsets, import and export reviews
-- Scripts to reset the knowledge base and repopulate it with the standard data files (Eric will expand)
-- Actually scales to all of chr20, includes AssessNA12878 that reads a VCF and itemizes it against the truth data set
-- ImportCallset can load OMNI, HM3, CEU best practices, mills/devine sites and genotypes, properly marking sites as poly/mono/unk as well as TP/FP/UNK based on command line parameters
-- Added shell scripts that start up a local mongo db, that connect to a local or BI hosted mongo for NA12878.db for debugging, and a setupNA12878db script that can load OMNI, HM3, CEU best practices, Mills/Devine into the db and then update the consensus.
-- Reviewed sites can be exported to a VCF, and imported again, as a mechanism to safely store the only non-recoverable data from the Mongo DB.
-- Created a NA12878DBWalker that manages the outer DB interaction, and that all MongoDB interacting walkers inherit from. Added a NA12878DBArgumentCollection.java consolating all of the common command line arguments (though strictly not necessary as all of this occurs in the root walker)
UnitTests
-- Can connect to a test knowledge base for development and unit testing
-- PolymorphicStatus, TruthStatus, SiteIterator
-- NA12878KBUnitTestBase provides simple utilities for connecting to the test mongo db, getting calls, etc
-- MongoVariantContext tests creation, matching, and encoding -> writing -> read -> decoding from the mongodb
AssessNA12878
-- Generic tool for comparing a NA12878 callset against the knowledge base. See http://gatkforums.broadinstitute.org/discussion/1848/using-the-na12878-knowledge-base for detailed documentation
-- Performs trivial filtering on FS, MQ, QD for SNPs and non-SNPs to separate out variants likely to be filtered from those that are honest-to-goodness FPs
Misc
-- Ability to provide Description for Simplified GATK report
