Obtained volumes can be really huge:
2048x2048x2048x4 (in float) = 32Gb per scan !!!!!
We cut each scan in 8 subfiles: 2048x2048x256x4=4Gb...
Grey level correspond directly to the lin
ear attenuation coefficient in cm-1 but these files can be difficult to manipulate for further treatments...

That's why we can rescale them to 8 bit files using 'mrecad' program.

On any NICE machine:

coralx> cd id19/volfloat

coralx> mrecad min max prefix_file*.vol

.raw files will be created automatically in 'volraw' dirextory.
