NGS Browser

(Removed) Visualize and explore alignments

The app has been removed. Use Genomics Viewer instead.


The NGS Browser app lets you visualize and explore the alignment of reads to a reference sequence.

You can:

  • Visualize short-read data aligned to a nucleotide reference sequence, and compare multiple data sets aligned against a common reference sequence.

  • View coverage of different regions of the reference sequence.

  • Investigate quality and other details of aligned reads.

  • Identify polymorphisms and visualize insertions and deletions.

  • Retrieve feature annotations relative to a specific region of the reference sequence.
