Have you heard about this new method to identify DNA?
New software, developed by cooperating teams of researchers from Columbia University and the New York Genome Center (NYGC), will help to quickly and accurately verify identity using DNA. The method involves using the MinION DNA sequencing device, a small, credit card sized device that is capable of sequencing 10-20 GB of data in real-time, along with off-the-shelf technology like what is available commercially through outlets like 23 & Me or Ancestry.com.
According to the study’s senior author Yaniv Erlich who is a professor of Computer Science at Columbia Engineering, an adjunct core member at NYGC, and a member of Columbia’s Data Science Institute, “Our method opens up new ways to use off-the-shelf technology to benefit society.” This research was published in the latest issue of the journal eLife.
In the two-step process, the researchers were able to take individual variants unique nucleotides) from DNA sequenced with the MinION and apply a probability algorithm (called a Bayesian algorithm) to compare each unique set of variants with corresponding variants in other genetic profiles in the database. With each cross-reference, the probability of verifying a match increases, narrowing the search. Testing has shown that the system is capable of verifying a match between 60-300 cross-references and it takes only minutes.(https://futurism.com/software-verify-id-dna/
