What is a .AB1 file?
AB1 is an ABIF chromatogram from Sanger DNA sequencing.
- Did you know
- AB1 holds the coloured peaks a sequencing machine reads to spell out DNA.
- AB1 is one extension for the ABIF standard, short for Applied Biosystems Interchange Format, the output of ABI Sanger sequencers.
- Beyond the coloured trace, an AB1 file also stores the machine’s base calls and the quality scores judging each one.
- What Analyser reads
- Identify and read more scientific, medical and engineering files: R serialized data (RDS/RData), ABIF sequencing traces, VASP/Gaussian/XCrySDen DFT structures, ChemDraw (CDX/CDXML), Axon ABF and NI TDMS instrument data, BrainVision/Neuroscan/EEGLAB EEG, Gmsh/Abaqus/Nastran/ANSYS FEA decks, SPICE netlists, VTK structured/rectilinear grids and oscilloscope waveforms.
- Depth of analysis
- .AB1 is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .AB1 file
- Drag a .AB1 file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
