Convert SEQ to another file type
To convert SEQ Sequences to another format, you need 4Peaks or other Data software.
Convert a file to SEQ
To convert other file formats to the "Sequence Data File" file type, you need software like 4Peaks or a similar tool.
About SEQ files
.SEQ files are highly fragmented, but they most commonly store DNA nucleotide sequence data used in bioinformatics, often formatted as standard plain text (FASTA format). Biologists use tools like 4Peaks or BioEdit to open them. A secondary, yet major, use is for video sequences, specifically storing uncompressed frames captured by high-speed industrial cameras using Norpix StreamPix or FLIR thermal imaging software.
The main disadvantage of .SEQ files is their extreme specialization. Bioinformatics .SEQ files are raw data that cannot easily be formatted or shared with non-scientists without dedicated software. Video .SEQ files pose a massive problem because they are proprietary, result in files that easily exceed 10GB, and are completely unsupported by standard video players or web browsers.
Converting your .SEQ file is the most pragmatic solution. For DNA data, convert to TXT or CSV to read the sequences in standard text editors or spreadsheets, or to FASTA for universal archiving. For video sequences, convert to MP4 (H.264) for web sharing and playback, or export to an image sequence like PNG for frame-by-frame analysis without losing quality.
Convert.Guru analyzes your SEQ file, detects the exact format, and lets you read the text inside.
If you want to convert SEQ file to FASTA, MP4, AVI, MIDI, MP3, WAV, AAC, FLAC, OGG, WMA, M4A or AIFF, you can use 4Peaks or similar software from the "DNA & Video Sequence Data" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to SEQ, try 4Peaks or another comparable tool in the "DNA & Video Sequence Data" category.
The SEQ Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SEQ converter.
