This figure shows multiple representations of a CA tandem repeat. The left shows five possible representations differentiated by color. The right shows the corresponding representation in VCF. The last representation represents the left aligned and parsimonious representation of the STR.

== How to observe that a variant is not left aligned or parsimonious on the right side? ==

== Is a variant normalized? ==

 

In order to detect if a variant is normalized, we first prove the following lemma.

     Each allele ends with the same nucleotide if and only if it is not left aligned or not right parsimonious.
