[Insight-users] [ANNOUNCE] ITK 4.4.0 has been released!

[Vladimir S. FONOV]

Hello,

if it is the same file as the one from the bigbrain project, it has 
dimensions of 1970x2330x1890 , stored as unsigned short (2bytes per 
voxel), and required approximately 32Gb of ram to load it in memory - 
MINCImageIO will load the whole volume into memory  as array of floats.

Also, the volume is stored in YZX order , with Y fastest varying, 
because ITK only allows using XYZ order the MINCImageIO transposes the 
volume as part of loading it into memory.

I have tried to load the whole volume into memory on a 64bit machine 
with 128Gb of ram using ITK-4.4 version and the test worked properly, 
although took a bit of time.

Maybe the error appears when the machine does not have RAM?
