SnapGene Viewer is a program specifically designed for molecular biologists to help them create, annotate, and print DNA sequence files. The utility supports various file formats, provides you with many editing options, and works 100%.
You have access to a sample file which you can analyze and alter the options for every built-in element. Afterward, you can create or import DNA sequence files, annotate them with just a few clicks, and immediately export or print the results.
A feature that's currently missing from the program is the access to an integrated help manual which might come in handy to people who are new to this type of utilities. Instead, you need to go to the homepage of the developer every time you need assistance while working with SnapGene Viewer.
Another thing you need to consider before downloading and installing this tool on your PC is that the developer provides you with another program that brings you more features (simulation, alignment with other sequences, history overview, etc.). However, the utility in question comes with a price.
In conclusion, it's up to you to decide, based on your needs and budget, if it's worth installing SnapGene Viewer on your PC or try another solution.
