摘要
In one embodiment, a method for identifying candidate sequences for genotyping a genomic sample comprises obtaining a plurality of sequence reads mapping to a genomic region of interest. The plurality of sequence reads are assembled into a directed acyclic graph (DAG) comprising a plurality of branch sites representing variation present in the set of sequence reads, each branch site comprising two or more branches. A path through the DAG comprises a set of successive branches over two or more branch sites and represents a possible candidate sequence of the genomic sample. One or more paths through the DAG are ranked by calculating scores for one or more branch sites, wherein the calculated score comprises a number of sequence reads that span multiple branch sites in a given path. At least one path is selected as a candidate sequence based at least in part on its rank.
