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

[Panagiotis Foteinos]

Dear all,
thank you for your advice.

Vladimir: yes, this is the right file. However, my 64bit system machine has
96GB of memory, so RAM is not a problem. Actually, no RAM is being used,
since it seems that the file is not even opened.

Bill: Would you still like a pointer to the file?

Best Regards,
Panagiotis
