Opening SEQ files

Did your computer fail to open a SEQ file? We explain what SEQ files are and recommend software that we know can open or convert your SEQ files.

What is a SEQ file?

The .seq or sequence file extension is found in files which are editable text file that normally contains a DNA sequence. The term editable in this type of file means that the data can be manipulated and the 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 run in different chromatogram software.

SEQ files are created by processing an .ab1 file (another file that can be derived using chromatogram software). SEQ came from .ab1. When you cut .ab1 into pieces, .seq files will be created, therefore, SEQ files are shorter than AB1 files. The trimming of .ab1 into .seq is done to further analyze the data in a DNA in a thorough but manageable way. Many DNA sequencing programs and viewed in a text editor can be used to view and edit .seq files. Some of them are the following: Genome Compiler, Heracle BioSoft DNA Baser, GSL Biotech SnapGene and DNASTAR Lasergene.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
