X:Fileformats

XTK supports a variety of scientific file formats out-of-the-box. We think that the best way to render your files is without any necessary conversions. Just drop'em on a webserver and they are ready to render.

Surface Models/Mesh Files

• .STL - Standard Tessellation (ascii and binary) * pretty-fast *
• .VTK - The Visualization Toolkit polydata (ascii only) * pretty-fast *
• .FSM, .INFLATED, .SMOOTHWM, .SPHERE, .PIAL, .ORIG - Freesurfer meshes * ultra-fast *
• .OBJ - Wavefront .obj format

DICOM/Volume Files

• .NRRD - Single file DICOM (compressed/uncompressed auto-detection)
• .NII - Single file DICOM in NIfTI1 format (uncompressed) * ultra-fast *
• .NII.GZ - Single file DICOM in NIfTI1 format (compressed)
• .MGH - Single file DICOM (uncompressed) * ultra-fast *
• .MGZ - Single file DICOM (compressed)
• .DICOM, .DCM - Multi file DICOM (uncompressed, raw) * ultra-fast *

Tractography Files

• .TRK - The default TrackVis file format for fiber tracks.

Scalar Overlay Files

• .CRV - Freesurfer Curvature measurements
• .LABEL - Freesurfer Labels

Color Table/Look-Up Table Files

• .TXT/.* - The file extension of color tables does not matter as long as they are in this format:
