b) Change md5 to reflect records that are now merged correctly.
c) Change unit merge alleles test to reflect the fact that a null non-variant vc object is not valid and not supported because there's no way to codify such object in a vcf. The code correctly converts this to a non-variant single-base event with whatever the reference is at that location.
With the current implementation, a read cannot start with a deletion or an insertion. Maybe this will change in the future, but for now, chop the leading insertion off.
b) First reimplementation of new vc merger of different types. Previous version did it in two steps, first merging all vc's per type and then trying to see if resulting vc's would be merged if alleles of one type were a subset of another, but this won't work when uniquifying genotypes since sample names would be messed up and GT sample names wouldn't match VC sample names. Now, it's actually simpler: when splitting vc's by type before merging, we check for alleles of one vc being a subset of alleles of vc of another type and if so we put them together in same list.
* Deletions now count as hard clipped bases in order to recover the original alignment start of a clipped read.
* Insertions do not count as hard clipped bases for the same reason.
* This created a bug in the previous cigar cleaning function. Fixed.
-We now assign a functional class (nonsense, missense, silent, or none) to each SnpEff effect, and add a
SNPEFF_FUNCTIONAL_CLASS annotation to the INFO field of the output VCF.
-Effects are now prioritized according to both biological impact and functional class, instead of impact only.
-Many of SnpEff's "low-impact" effects are now classified as "modifiers" with lower priority than every
other effect. This includes such "effects" as DOWNSTREAM, UPSTREAM, INTRON, GENE, EXON, and others that
really describe the location of the variant rather than its biological effect.
This code will be short-lived (likely 1.2-only), as the next version of SnpEff will include most of these
features directly.
Checking this change into Stable+Unstable instead of Unstable because the current functional class stratification
in VariantEval is basically broken and urgently needs to be fixed for production purposes.
if soft clipped bases were after a hard clipped section of the read, the hard clip was clipping the left soft clip tail as if it were a right tail. Mayhem.
* Hard clipped Cigar now includes all insertions that were hard clipped and not the deletions.
* The alignment start is now recalculated according to the new hard clipped cigar representation
