MultiTracer version 2

MultiTracer is a Java application for use with volumetric imaging data. MultiTracer allows:

Visualization of volumetric structural data and inspection of time courses of functional data
Manual editing to remove unwanted anatomic features
Manual delineation of anatomic boundaries
- simple measures such as volumes, areas and lengths can be quantified directly
- boundaries can be exported for more detailed measures using other software tools
- creation of mask volumes corresponding to delineated anatomic strucures

Current Version

The current version of MultiTracer (version 2) was released on August 29, 2012. You can verify that you have the latest release by checking the "About" menu item under the "File" menu.

Requirements

Java 1.6 (i.e., version 6) or higher (available for PCs, Mac OS X, and most UNIX platforms)
Images must be 3D or 4D grayscale images (big-endian or little-endian) in one of the following formats:
- Neuroimaging Informatics Technology Initiative NIfTI-1.1 or NIfTI-2 formats [Note: some NIfTI-2 files with certain features that cannot be encoded in NIfTI-1.1 format are not supported]
  - Integer formats
    - 8 bits/voxel
      - signed char (DT_INT8 datatype=256)
      - unsigned char (DT_UINT8 datatype=2)
    - 16 bits/voxel
      - signed short (DT_INT16 datatype=4)
      - unsigned short (DT_UINT16 datatype=512)
    - 32 bits/voxel
      - signed int (DT_INT32 datatype=8)
      - unsigned int (DT_UINT32 datatype=768)
  - Floating point formats (editing not supported)
    - 32 bits/voxel
      - float (DT_FLOAT32 datatype=16)
    - 64 bits/voxel
      - double (DT_FLOAT64 datatype=64)
- Analyze 7.5 format (legacy support)
  - 8-bit unsigned character data (DT_UNSIGNED_CHAR type code=2)
  - 16-bit signed short data (DT_SIGNED_SHORT, type code=4)
  - 16-bit unsigned short data (derived, glmax>32767, not a standard Anayze 7.5 format)

Please note that MultiTracer version 2 does not support several file formats that were supported in the original version of MultiTracer. Please use the original version of MultiTracer if you require support for: Medical Image NetCDF (MINC) format, uncompressed Tagged Image File Format (TIFF), zipped TIFF format, Graphics Interchange Format (GIF), Joint Photographic Experts Group (JPEG) format, Bitmap format (BMP), Flexible Images Transport System (FITS) format, or raw voxel data. Converters to NIfTI format for these and other formats (e.g., DICOM) may also be available.
