LONI Visualization Tool (LONI_Viz)®
Input Data Type & File Formats

• LONI_Viz reads in 1, 2 or 3D (dimensional) (GZIPed or uncompressed) data sets of the following types:
• RAW BINARY (ANALYZE) data files having the following name convention: myFile.img
  And auxiliary ANALYZE or ASCII header files RAW-HEADER with data types as follows:
  • 8 bit (byte), range [0 : 255], code: 8;
  • 8 bit (byte), range [-128 : 127], code: 9;
  • 16 bit (unsigned) short integer data, range [0 : 65535], code: 16;
  • 16 bit (signed) short integer data, range [-32768 : 32767], code: 17;
  • 32 bit (unsigned-integer), code: 32
  • 32 bit (signed-integer), code: 33
  • 32 bit (float), code: 34
  • 64 bit (double), code: 64
    
  Note: "code" refers to the data-type listed in the auxiliary header file, where for example a line like "data_type=16" is equivalent to "bits/pix=16" and both mean 16 bit (2 byte) unsigned data (short integer).
• Network Common Data File format - Net CDF (NC), and its specialization Montreal Net CDF - Minc (MNC)
• DICOM DICOM files could be visualized as 2D series of images (default), or if renamed to file###.dicom and saved in a single directory the series could be used to reconstruct a Montreal Net CDF file (mnc) and visualized in 3D. To do this DICOM --> MNC conversion you need to have all dicom files into a new directory. Select the directory from the File-->Load menu (not any one file) and it will grab all dicom files and reconstruct the 3D stereotactic data representation in a MNCDF file, which you can finally load in.
• Various rasterized image formats (e.g., TIFF, GIF, etc.)
  
• Starting LONI_Viz is done by either of:
  • WINDOWS: click on the "LONI_Viz_driver.bat" icon
  • UNIX%> LONI_Viz_driver
  • UNIX%> LONI_Viz_driver myFile
  • UNIX%> java LONI_Viz2
  • UNIX%> java LONI_Viz2 myFile
  • other%> java -jar LONI_Viz.jar [file]
