SEQ File - opening and understanding
Did your computer fail to open a SEQ file? We explain what they are used for and recommend software that we know can open or otherwise handle 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.
How to open SEQ files
You will need a program compatible with the specific file you are trying to open, as different programs may use files with file extension SEQ for different purposes.
While we have not verified the apps ourselves yet, our users have suggested 10 different SEQ openers which you will find listed below.
Suggest another file format using extension SEQ
While we know of one file format using the .SEQ file extension, there may be more. It is widespread that different programs use files with the same file extension for very different types of data. Please let us know if you are aware of a different kind of .SEQ file.

These apps are known to open certain types of SEQ files. Remember, different programs may use SEQ files for different purposes, so you may need to try out a few of them to be able to open your specific file.
