SEQ File

What are SEQ files and how to open them

Are you having problems opening a SEQ file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your SEQ files.

What is a SEQ file?

SEQ files have multiple uses, and DNA Sequence is one of them. Read more about the other uses further down the page.

DNA Sequence File

These files are editable text files that contain a DNA sequence. Editable, in this case, means that users can manipulate the data, and that results can sometimes be derived from it. Character possibilities are often projected based on the desired DNA Sequence set up, and the files can also be saved in other formats to be used in different chromatogram software.

SEQ files are created by processing an AB1 file (another file that can be derived using chromatogram software).

When you cut .ab1 into pieces, .seq files will be created. Therefore, SEQ files are shorter than AB1 files. Trimming of AB1 files into SEQ files is done to further analyze the data in a DNA Sequence in a thorough but manageable way.

You can use many DNA sequencing programs to view and edit .seq files.

How to open SEQ files

We have identified four SEQ openers that are compatible with this specific type of SEQ file.
