File format
All data sets are stored in a simple binary format. It consits of a 6 byte header which contains the data set dimensions (one unsigned 2 byte value per dimension) followed by the voxel data (one unsigned 2 byte value per voxel) in sequential slice-by-slice order. The data range is [0,4095]. The format uses little-endian byte order. Here is a simple C++ code snippet to read such a file into an array:
FILE *fp = fopen("filename.dat","rb");
unsigned short vuSize[3];
fread((void*)vuSize,3,sizeof(unsigned short),fp);
int uCount = int(vuSize[0])*int(vuSize[1])*int(vuSize[2]);
unsigned short *pData = new unsigned short[uCount];
fread((void*)pData,uCount,sizeof(unsigned short),fp);
fclose(fp);
