What is a .FTS file?
FTS is a Flexible Image Transport System file holding astronomical imaging or data.
- Did you know
- FITS has been astronomy’s data standard since 1981.
- A FITS header is composed of fixed 80-character “cards”, a width carried over from punch-card systems.
- The format follows the motto “once FITS, always FITS”, so revisions to the standard must remain backward compatible.
- 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
- .FTS 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 .FTS file
- Drag a .FTS 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.
