- Hans J. Johnson Analyze image file sets consist of at least 2 files: REQUIRED:
- an image file ([basename].img or [basename].img.gz or [basename].img.Z) This contains the binary represenation of the raw voxel values. If the file is uncompressed, it should be of of size (sizeof(storagetype)*NX*NY*NZ(*NT). The format of the image file is very simple; containing usually uncompressed voxel data for the images in one of the several possible voxel formats:
- 1 bit packed binary (slices begin on byte boundaries)
- 8 bit (unsigned char) gray scale unless .lkup file present
- 16 bit signed short
- 32 bit signed integers or float
- 24 bit RGB, 8 bits per channel
- a header file ([basename].hdr) This a 348 byte file 99.99% of all images that contains a binary represenation of the C-struct defined in this file. The analyze 7.5 header structure may, however, be extended beyond this minimal defintion to encompase site specific information, and would have more than 348 bytes. Given that the ability to extend the header has rarely been used, this implementation of the Analyze 7.5 file will only read the first 348 bytes into the structure defined in this file, and all informaiton beyond the 348 bytes will be ignored. OPTIONAL:
- a color lookup file ([basename].lkup) The .lkup file is a plain ASCII text file that contains 3 integer values between 0 and 255 on each line. Each line of the lkup file represents one color table entry for the Red, Green and Blue color components, respectively. The total dynamic range of the image is divided by the number of colors in color table to determine mapping of the image through these colors.
For example, an 8-color 'rainbow colors' lookup table is represented as:
255 0 0 255 128 0 255 255 0 128 255 0 0 255 0 0 0 255 128 0 255
255 0 255
- an object file ([basename].obj) A specially formated file with a mapping between object name and image code used to associate image voxel locations with a label. This file is run length encoded to save disk storage.
