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.

File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.
If you have additional information about the SEQ file format or software that uses files with the SEQ suffix, please do get in touch - we would love hearing from you.
