Short-read DNA sequencers have trouble identifying large structural variants. These could be in the form of copy number variants, translocations, duplications, deletions, insertions, and inversions. The TELL-Seq™ WGS Library Prep kit links short-reads turning them into long-reads. The linked, long-read data that you get using the TELL-Seq™ kit will allow you to take a step back and see what you were missing.
