    Abstract: Systems and method for identifying long deletions can obtain sequencing information for a plurality of amplicons in and around a potential region from a nucleic acid sample. The sequencing information can include a plurality of reads that can be mapped to a reference sequence. Using information, such as where reads map to a reference sequence and relative abundance of reads for the amplicons, structural variants can be identified and a determination can be made if the nucleic acid sample is homozygous or heterozygous for the structural variant.

    Abstract: A method for evaluating variant likelihood includes: providing a plurality of template polynucleotide strands, sequencing primers, and polymerase in a plurality of defined spaces disposed on a sensor array; exposing the plurality of template polynucleotide strands, sequencing primers, and polymerase to a series of flows of nucleotide species according to a predetermined order; obtaining measured values corresponding to an ensemble of sequencing reads for at least some of the template polynucleotide strands in at least one of the defined spaces; and evaluating a likelihood that a variant sequence is present given the measured values corresponding to the ensemble of sequencing reads, the evaluating comprising: determining a measurement confidence value for each read in the ensemble of sequencing reads and modifying at least some model-predicted values using a first bias for forward strands and a second bias for reverse strands.
