Extract text from SnapGene sequences (DNA)
To convert DNA sequences to another format, you need SnapGene or other Data software.
To convert other file formats to the "Bioinformatics Sequence File" file type, you need software like SnapGene or a similar tool.
The .dna file extension is predominantly used by SnapGene, a specialized molecular biology software developed by GSL Biotech. These files act as digital containers for annotated DNA sequences, plasmid maps, and cloning simulations. Less frequently, .dna files contain 3D digital human character rig data for the Epic Games MetaHuman framework, or act as legacy backups for older Computer Associates software.
Biologists and researchers use SnapGene or the free SnapGene Viewer to analyze the complex genetic constructs inside these files. You can learn more about the underlying biological processes at Wikipedia's DNA sequencing page.
The primary disadvantage of the .dna format is its strictly proprietary structure. While it excels at holding rich genetic annotations, custom visual coloring, and detailed history trees, you cannot view this data without installing specific, heavy desktop software. Because it relies on complex binary formatting, simply opening a .dna file in a standard text editor results in corrupted, unreadable characters. This poses a major barrier when collaborating with scientists or 3D artists who do not hold a software license.
To share genetic sequence data universally, you must convert .dna to open bioinformatics standards. The best conversion targets are FASTA for raw text-based ATCG sequences, or GenBank GBK format to preserve the feature annotations. If you need to share the visual plasmid map, exporting to PDF or PNG is ideal, though you will lose the computable genetic string.
Because .dna is a closed, proprietary format, standard online converters often fail to process it. Usually, only the original software can properly read or export the highly specific annotation data. If our analysis detects a supported embedded format, viewing or conversion to plain text may still be possible.
Convert.Guru analyzes your DNA file, detects the exact format, and lets you read the text inside.
Users also converted GDNA, GBK, GZ, VCF, TXT, DNG, MP3, CSV, PDF, SLDPRT, SPV, ZIP and MUSIC files.
If you want to convert DNA file to MUSIC, BAK, BACKUP, OLD, TMP, TEMP, ARC, ZIP, TAR, GZ, 7Z or RAR, you can use SnapGene or similar software from the "DNA Sequence & Annotation Storage" category. In the File menu, look for Save As… or Export….
To convert SNAPSHOT, OLD, IMG, RESTORE, ISO, COPY, VMDK, TMP, VHD, BAK, ARCHIVE or BACKUP files to DNA, try SnapGene or another comparable tool in the "DNA Sequence & Annotation Storage" category.
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 DNA converter.
