BrainVoyager QX file formats

Due to the fact that BrainVoyager should be able to use the same files on all supported platforms (Windows, Linux, Mac), own, plaform independent file formats have been created to make sure this goal can be easily achieved.

To read in BrainVoyager files into Matlab, the new BVQXtools toolbox is under development, allowing more flexible and compatible input and output functionality within MATLAB. From Matlab, the BrainVoyager scripting commands can be invoked using the Microsoft Component Object Model (COM) technology. For more information, please consult the 'Scripting BrainVoyager from Matlab' guide that can be found in the Reference manuals section of the scripting documentation page.

Naturally, in later versions the file formats were extended, maintaining backward compatibility within the program. To simplify the generation of third-party code interacting with BrainVoyager, please find below a list of file formats currently used in BrainVoyager QX along with the details given for each respective format. A downloadable version of the BrainVoyager QX file formats documentation can be found below.

MR Data (project) file formats

Functional data

• FMR file format (functional MR project, text file, referencing STC files)
• STC file format (slice time course data)
• VTC file format (volume time course data)(document in *.pdf)

Anatomical data

• AMR file format (anatomical MR project, coplanar to FMR/STC project/files)
• VMR file format (high resolution volumetric MR data)
• V16 file format (16-bit based VMR, native data!)

Vertex / mesh based files

• MTC file format (mesh time course data)
• SRF file format (surface file)(graphical depiction of file contents in *.pdf)

Auxiliary files

• POS file format (positioning files, text file)
• TAL file format (talairach coordinates file, text file)
• TRF file format (transformation file, text file, rigid body)

experiment / GLM / statistics file formats

User specified files

• PRT file format (protocol file, text file, conditions and onsets)

Files usually created by BVQX

• RTC file format (single-subject design matrix or generic reference time course, text file with numeric matrix)
• SDM file format (single-run design matrix (BVQX 1.9.10 and higher))

Group study files

• MDM file format (multi-study design matrix, text file referencing RTCs and VTCs)

Result files

• GLM file format (General Linear Model results file)
• MAP file format (map of slice-based results, any stastical test)
• VMP file format (5) (volumetric map of VTC-based results, any stastical test)(document in *.pdf)
• SMP file format (surface map of MTC-based results, any stastical test)
• AVG file format (file with event-related averaging results)

Auxiliar files

• VOI file format (voxel of interest, text file giving coordinates)
• VVD file format (voxel of interest, text file giving coordinates)

Additional file formats

Transformation files

• SSM file format (sphere to sphere vertex mapping information)

Visualization files

• VWP file format (viewpoint information)

User defined files

• UFF file format (user defined file format)(document in *.pdf)
