Sometimes it is useful to understand the working mechanism of a specific file format supported by NeuroElf/xff, particularly for the text-based (tff) formats (e.g. BrainVoyager QX's protocol file format). This page will, in time, link to information about the various formats.

• CMP, GCM, and ICA (BrainVoyager QX combined format for component, Granger, and ICA maps)
• GLM (BrainVoyager QX general-linear-model file, storage of regression results)
• HDR and NII (Analyze/NIftI file format, multi-purpose storage of 3D/4D voxel-wise data)
• MAP (BrainVoyager QX slice-based map file, i.e. for FMR overlay)
• MAT (Matlab MAT file with data field)
• MSK (BrainVoyager QX mask file, voxel-based)
• MTC (BrainVoyager QX mesh-based timecourse file)
• SMP (BrainVoyager QX surface map file, i.e. for SRF overlay)
• SRF (BrainVoyager QX surface file, vertices, triangles, normals, colors)
• SSM (BrainVoyager QX surface-to-surface mapping file, maps vertices from one to another surface)
• STC (BrainVoyager QX slice-based timecourse file, actual data referenced in FMR files)
• VMP (BrainVoyager QX voxel-based map file, i.e. for VMR overlay)
• VMR (BrainVoyager QX voxel-based MR file, i.e. anatomical data)
• VTC (BrainVoyager QX voxel-based timecourse file)

• FMR (BrainVoyager QX Functional MR file)
• HEAD (AFNI HEAD/BRIK file)
• MDM (BrainVoyager QX Multi-study design matrix file)
• OLT (BrainVoyager QX Overlay Look-up Table file)
• POI (BrainVoyager QX Patch-Of-Interest file)
• PRT (BrainVoyager QX Protocol file)
• SDM (BrainVoyager QX Single-study design matrix file, supercedes the older RTC format)
• TAL (BrainVoyager QX Talairach transformation file)
• TRF (BrainVoyager QX Transformation file)
• VOI (BrainVoyager QX Volume-Of-Interest file)
