What is a .VTI file?
VTI is a VTK XML file holding a regular grid of values, such as a volume.
- Did you know
- VTI stores image and volume data on a regular grid for VTK.
- VTI is the .vti member of VTK’s XML family, holding vtkImageData - values on an evenly spaced grid such as a 3D volume.
- Its payload can be stored as ASCII, Base64 or raw appended binary, with optional compression for large datasets.
- 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
- .VTI 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 .VTI file
- Drag a .VTI 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.
