(To be removed) Open NGS Browser to visualize and explore alignments

ngsbrowser will be removed in a future release. Use Genomics Viewer instead.


ngsbrowser opens the NGS Browser app.

ngsbrowser(bmObj) imports the BioMap object bmObj and opens it in the NGS Browser app.

Input Arguments

collapse all

Object containing sequence information or short-read sequence alignment data, specified as a BioMap object.


collapse all

Create a BioMap object from a SAM-formatted file.

b = BioMap('ex1.sam');

Display the object in the NGS Browser.



  • Use the NGS Browser to compare the alignment of multiple data sets to a common reference sequence.

  • Use the NGS Browser to investigate regions of interest in the short-read alignment determined by various analyses, such as RNA-Seq, ChIP-Seq, and genetic variation analyses.
