What is a CM5 file?

CM5 files mostly belong to SnapGene. CM5 files are used to store DNA sequence data in sequencing projects. They are known as Chromas sequencing project files, and they capture raw sequence information along with trace and quality details.
These files are created by sequencing instruments and are managed using specialized software like SnapGene. Their content includes nucleotide sequences and may also contain metadata that helps assess sequence quality.

Contain raw DNA sequence data
Include information on base-call quality and signal intensity
Require specific bioinformatics tools for proper viewing and analysis

How can I open a CM5 file?

You need a suitable software like SnapGene to open a CM5 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your CM5 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CM5 file directly in the browser:. Just drag the file onto this browser window and drop it.

How to solve problems with CM5 files

Associate the CM5 file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest CM5 file format. Search, therefore, e.g. on the manufacturer website after an available SnapGene update.
To make sure that your CM5 file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
