What is a .FAA file?
FAA is a FASTA file holding amino-acid (protein) sequences.
- Did you know
- The .faa suffix marks a FASTA file as protein sequences.
- The FASTA format takes its name from Pearson and Lipman’s “FAST-All” search program, reflecting its use across sequence types.
- In a FASTA file proteins are spelt out in single-letter amino-acid codes beneath a “>” header line.
- 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
- .FAA 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 .FAA file
- Drag a .FAA 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.
