  • Publication number: 20240120021
    Abstract: Computational methods used for large scale scaffolding of a genome assembly are provided. Such methods may include a step of applying a location clustering model to a test set of contigs to form two or more location cluster groups, each location cluster group comprising one or more location-clustered contigs; a step of applying an ordering model to each of the two or more location cluster groups to form an ordered set of one or more location-clustered contigs within each cluster group; and a step of applying an orienting model to each ordered set of one or more location-clustered contigs to assign a relative orientation to each of the location-clustered contigs within each location cluster group. In some aspects, the test set of contigs are generated from aligning a set of reads generated by a chromosome conformation analysis technique (e.g., Hi-C) with a draft assembly, a reference assembly, or both.

  • Publication number: 20220403371
    Abstract: Provided herein are methods and systems for identifying chromosomal structural variants in a preserved sample obtained from a subject using focused acoustic energy and chromosomal conformational capture. Also provided herein are methods and systems for relating the chromosomal structural variants identified from the preserved tissue sample to diseases or disorders, and methods of treating same.

  • Patent number: 9670495
    Abstract: A DNA sequence that functions as an origin in many different yeast species. From 1 to 17 mutations can be introduced into this sequence to improve its function across multiple yeasts. The resulting synthetic DNA sequence confers stable plasmid replication function in all yeast species tested, including but not limited to Saccharomyces cerevisiae, Lachancea kluyveri, Kluyveromyces lactis, Kluyveromyces wickerhammii, Hansenula polymorpha, and Pichia pastoris. Also provided are sequences that function as an optimal origin in the industrially useful Pichia pastoris.
