Text files
Some of the BrainVoyager file formats can be read in text processing applications. These are:
- *.pos (Position and scanner data)
- *.prt (Stimulation protocol file)
- *.ttf (t-test file)
- *.ctr (Contrast definition for General Linear Model)
- *.voi (Voxels of interest file)
- *.rtc (Reference time course)
- *.asc (ICA generated file or time course)
- *.trf (Description of rigid body transformation)
- *.tal (Talairach coordinates)
- *.mdm (Multiple subject study design)
- *.avg (Event related averaging)
- *.log (Log file created during interpolation or transformation)
- *.vwp (Viewing points in surf module)
- *.dat (Event related averaging)
- *.ads (Design for Ancova analysis)
It is not recommended to change these files manually, while an unintentional typing error might cause that BrainVoyager cannot properly read the file.
File that can be read by video player programs:
- *.avi (Movie file, created during motion correction)
Binary files
Files that contain the fMRI image data or other binary data cannot be read directly. This is the case for:
- *.amr (Slice based anatomical MRI data)
- *.vmr (Volume based anatomical MRI data)
- *.v16 (Volume based anatomical MRI data,
16 bits)
- *.srf (Cortex based anatomical MRI data)
- *.stc (Slice time course)
- *.vtc (Volume time course)
- *.mtc (Mesh time course)
- *.map (Slice based statistical overlay map)
- *.vmp (Volume based statistical overlay map)
- *.smp (Cortex based statistical overlay map)
- *.glm (Statistical data - General Linear Model)
- *.ssm (Sphere to sphere vertex mapping)
- *.pmp (Spherical map (coordinates))
- *.fmr (Functional fMRI data)
- *.msk (Mask file used for statistical analysis)
- *.ica (Independent Component Analysis file)
- *.ava (Results of Ancova computation)
It is possible to read some of these BrainVoyager files via tools like Matlab. Of course it is also possible to write a stand alone program in for example C++ to read the files. A detailed description of the file formats is provided in the BrainVoyager User's Guide, chapter 'File formats'.
Export from BrainVoyager to the following file formats:
- *.dcm (DICOM file with activation displayed;
on the basis of non-transformed DICOM files that is readable by BrainVoyager)
- *.hdr (Analyze header file from any other raw fMRI format that is readable
by BrainVoyager)
- *.img (Analyze image file from any other raw fMRI format that is readable
by BrainVoyager)
- *.stl (Stereolythographic format from *.srf file)
- *.wrl (Virtual Reality Modeling Language (VRML) file from *.srf)
- *.dxf (AutoCAD from *.srf)
