GRIDSS2 is the first structural variant caller to explicitly report single breakends—breakpoints in which only one side can be unambiguously determined. By treating single breakends as a fundamental genomic rearrangement signal on par with breakpoints, GRIDSS2 can explain 47% of somatic centromere copy number changes …Assuming that flanking sequences near SSRs were highly conserved, SSRMMD allowed flanking sequences near SSRs to tolerate up to 2-bp mismatches. Moreover, after extensive assessments, additional mismatches (≥3 bp) did not further benefit the results, consistent with the aforementioned assumption. SSRMMD iteratively replaced mismatched bases ... The digest was run on a TBE acrylamide gel and analyzed by fluorescent imaging. The double stranded oligos were designed to have the indicated number of base pairs from the end followed by the recognition sequence and an additional 12 bases. In some cases asymmetric cleavage was observed and interpreted as a negative result. The early search algorithms were unable to account for structural variants, such as G4s with longer loops, bulges or mismatches, for two-tetrad G4s or for the importance of flanking sequences.
