a) Sites were numerically well behaved now, but another hard fact of life is that the AF iteration is defined in linear Pr space, not in log likelihood space, and the math doesn't work out in log space. So, we need to convert back and forth from lin to log space.
b) As a consequence of a), the code got a major slowdown, and calling the 629 samples was about 15 times slower than before (sic).
c) To solve b), log10 of integers are now cached at init, and numerical approximations are now made. Most importantly, I'm using the approximation that log(exp(a) + exp(b)) ~= max(a,b) which seems almost inconsequential in practical performance but reduces computation time to what it was before. More detailes analyses are forthcoming. This approximation can be refined further on to avoid expensive log-exp conversions if further profiling and analysis deems it necessary.
Also, two other issues were solved:
a) Strand bias computation was actually wrong in the case where the optimal AC was bigger than max(forward reads,reverse reads). Now the code is exactly as buggy as the grid search model (all bugs are equal, but some are more equal than others)
b) Genotype likelihoods are now computed in a better way and if a likelihood < 0 we don't just cap to 0 but do something a bit smarter.

a) Fix it up because it broke with a recent checkin to annotate vcf with unfiltered depth.
b) Printout of ref/alt alleles in output vcf was incorrect because the start/stop positions of associated GenomeLoc were incorrectly computed in case of a deletion.
c) Redid Beagle input/output walkers as not assume that ref was a single base, not to assume that variant was a vcf and generalized it to be indel-capable, so now the Beagle walkers can be used for indels as well.

Queue GATK generated .intervals is now a List(File) again removing special case handling in the generator.
Instead of using @Scatter annotation, using ScatterFunction instance to determine if a job can be scattered.
Implemented special VcfGatherFunction which only uses the header from the first file, even if the other files differ in their headers.

some subset need
A C 1/1 --> C A 0/0
while another subset need
A C 1/1 --> C A 1/1
it's unclear how big these subsets are (or even if one is empty). What I do know is, doing the first one totally screws up concordance metrics for the 421-sample chip. So either something else needs to be done, or there's a bug in this walker. Until I know for sure, I've added an initialize exception to disable this thing...

Modified - SelectVariants: Hook up to VariantContextUtils to recalculate AC/AF/AN, which uses the accessor in VariantContext to do this. Somehow sites that were selected down to hom-ref genotypes only wound up getting positive AC.
**IMPORTANT** I kind of need input here. The header of a file used for an integration test specifies AC as being an integer. Recalculating it casts it into an integer list (which it should be, as it allows for alternate alleles). However this appears to clash with what the jexl expression is looking for? For now, the integration test itself needed to be changed -- it's unclear what to do when the header specifies AC of being one class, but recalculating it casts to another class, and I'm not sure what to do.
I'm committing my omni_qc pipeline because I'm almost certain 2 months down the road I'm going to wonder what the heck I did to generate my results.

1: -sample can now include a file, which will be parsed for sample-name entries
2: If you request a sample to run analysis on, but it is not present in any of your RODs, VEW will exception out
3: Change added to parse Integer, String, and List<Integer> type Allele Count annotations (error otherwise)
4 [slightly problematic]: The count objects now maintain row-keys in order, as the keys were taking an inordinate amount of time in onTraversalDone (multiple calls to getRowKeys(), so many multiple sorts of the same underlying unsorted object, very bad)
There is a legacy comparison object which is unused which I will strip out soon.

The core walker has been modified so that when variant contexts (eval and comp) are subset to command-line-specified sample(s), the chromosome count annotations (AC/AN/AF) are altered to reflect the AC/AN/AF of only those samples involved in the comparison. No more getting AC500 when you're comparing a 10-sample overlap. Interestingly enough, this didn't break any integration tests.
GenotypeConcordance now has two additional tables: Allele Count Statistics, and Allele Count Summary Statistics. These work exactly identically to the Sample Statistics and Sample Summary Statistics tables, except that the partition being used is no longer the sample, but instead the allele count of the variant sites. These tables stratify by both eval and comp ACs, e.g.
evalAC0
evalAC1
evalAC2
compAC0
compAC1
compAC2
Differences with previous integration tests were verified to only be in the Allele Count tables (by grepping them out of the diff); a new test has been added for the simple case of an AC=1 site in the eval becoming an AC=2 site in the comp.

by the fact that the GATKSAMRecord, by design, needs to both inherit from
SAMRecord and wrap a 'member' SAMRecord, and method calls that aren't
implemented as explicit passthroughs can compromise the content of the
SAMRecord in subtle ways.
Will be automatically fixed when Picard moves to a lightweight SAMRecord
interface rather than the current heavyweight implementation. But in
the short-term, there's no obvious fix.

a) In Indel genotyper: we can't deal yet with extended events correctly and we are still triggering at each extended event which results in repeated records on a vcf. So, to avoid this, keep track of start position of candidate variantes we've visited and if we've visited a variant before we don't do it again.
b) Avoid infinite terms in QUAL and in genotype likelihoods which can happen if posterior AF happens to be exactly zero. For now, hard-code a minimum value of each term of the posterior AF likelihood to be -300 (ie 1e-300 in lin space). This can be solved with better and smarter log-to-lin conversions and some precision fixes in AF calculation.

Previous output spec contained 3 columns:
haplotypeReference,haplotypeAlternate,haplotypeStrand
where haplotypeReference was always on the + strand, and haplotypeAlternate was on the strand specified by haplotypeStrand.
The new specification contains 3 columns:
haplotypeReference,haplotypeAlternate,transcriptStrand
where haplotypeRef and haplotypeAlt are required to be on the + strand. transcriptStrand now specifies the strand of the transcript, which is needed for interpreting the haplotypes.

Queue now submits new LSF jobs only after previous functions have completed successfully.
When the Queue process is shutdown (ex: via Control-C) sends a bkill command for any running jobs.
Ported commands like creating directories and scatter/gather interval list to scala functions.
Updates to LSF status tracking by porting the python to internally generated bash scripts.
Temporarily disabled job name submission to LSF. Plus side is that the full command is now available in "bjobs -w". TODO: Put back jobName passing to LSF based on an option?
Changed BaseTest to allow scala to access paths to references.
Changed the extension generator to default the analysis name to the walker "name".

- Brought over exact AF estimation from branch (which is now dead). Exact model is default in UnifiedGenotyperV2.
- Implemented completely new genotyping algorithm given best AF estimate using dynamic programming, which in theory should be better than both greedy search and any HWE-based genotyper.
- Integrated and added new Dindel likelihood estimation model.
- Corrected annotators that would call readBasePileup: since we can be annotating extended events, best way is to interrogate context for kind of pileup and either readBasePileup or readExtendedEventPileup.
All changes above except last one are still in playground since they require more testing.
