What is a .FA file?
FA is a FASTA file of DNA, RNA or protein sequences.
- Did you know
- FASTA is the simplest and most common way to store biological sequences.
- FASTA was created in 1985 by William Pearson and David Lipman for their sequence-search software, and was once called the “Pearson format”.
- Each record opens with a “>” description line followed by the sequence written in single-letter residue codes.
- What Analyser reads
- Open scientific, medical and engineering files: DICOM scans, NIfTI brain volumes, Garmin FIT/TCX activities, FITS astronomy frames, FASTA/FASTQ sequences, chemistry structures (MOL/SDF/MOL2/CIF/XYZ), Gerber/Excellon PCB data, SPICE netlists, EDF/BDF biosignals, JCAMP-DX spectra, SPSS/Stata/SAS datasets and VTK/ParaView meshes - metadata extracted entirely in-browser.
- Depth of analysis
- .FA 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 .FA file
- Drag a .FA 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.
