This track collection contains structural variant (SV) calls derived from long-read sequencing studies. Structural variants are genomic rearrangements larger than ~50 bp, including deletions, insertions, duplications, inversions, and translocations. Long-read sequencing technologies can span repetitive regions and resolve complex rearrangements that are difficult to detect with short-read methods. The long read datasets described below were produced with one of two sequencing technologies, Oxford Nanopore Technologies (ONT) or Pacific Biosciences (PacBio, whose highly accurate reads are also called -HiFi, unlike the longer but less accurate CLR, Continous Long-Reads).
+HiFi, unlike the longer but less accurate CLR, Continuous Long-Reads).SV length statistics (min / median / max) use the size of the variant in base pairs: the inserted-sequence length for insertions and the reference span for deletions and other types. (For insertions the svLen reference-span field is only a 1-2 bp placeholder, so the inserted length is reported instead.) Some tracks include sites of length 0, complex events where the reference and alternate alleles differ in sequence but not in length. For example, two different insertions, one in either sequence, is usually called a "complex" event.
