Detailed Description

All subvolumes are stored in an array of MRI_IMAGE (the "brick").
  • If mmap is used, then the whole external file is mmap()-ed in one block and the data pointers for each image computed from this base.
  • If malloc() is used, then each image is separately allocated and read in.
  • Each datablock has a brick, even if it doesn't actually contain data (is only warp-on-demand).
  • Whether or not a datablock contains actual voxel data can be determined by examining the "malloc_type".
