Overview of the GASVPro. Fragments from a test genome are sequenced and the resulting paired reads are aligned to the
reference. A fragment may either have a unique mapping or be ambiguous with multiple
alignments to the reference. Following clustering of alignments (with GASV), the set
of possible structural variants and the fragments whose alignments support these
variants are recorded in the alignment matrix A. As each fragment originates from a single location in the test genome, a fragment
supports at most one structural variant. Thus, the mapping matrix M records the 'true' mapping for each fragment. GASVPro scores mapping matrices according
to a generative probabilistic model that incorporates concordant mappings. GASVPro
utilizes an MCMC procedure to efficiently sample over the space of possible mapping
matrices defined by the alignment matrix A. The underlying probabilistic model can be easily generalized to consider additional
features indicative of a 'true' mapping, such as the empirical fragment length distribution
or probability of sequencing errors.
