Would you like to move beyond hand-drawn plasmid maps?

SnapGene Viewer is revolutionary software that allows molecular biologists to create, browse, and share richly annotated DNA sequence files up to 1 Gb in length.


  • Create a DNA sequence file by either entering a sequence, or importing a record from GenBank, or opening an annotated sequence stored in one of many common file formats.
  • Browse or print a DNA sequence and its annotations using customizable Map, Sequence, Enzymes, Features, Primers, and History views.
  • Search a DNA sequence to match either a DNA query, or a protein translation, or an annotation.
  • View and edit DNA sequence traces.


  • Automatically annotate common features, or manually annotate coding sequences and other features.
  • Design and annotate primers for PCR, sequencing, or mutagenesis.
  • Identify open reading frames (ORFs) with a single mouse click.


  • Export a plasmid map as an image, or export an annotated DNA sequence to GenBank format.
  • Freely share data with your colleagues or customers using the universally accessible SnapGene format.

To install SnapGene Viewer, run the following command from the command line or from PowerShell:

C:\> choco install snapgene-viewer

To upgrade SnapGene Viewer, run the following command from the command line or from PowerShell:

Virus Scan Results

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.


This package has no dependencies.
