[Insight-users] Memory prblem: failed to allocate memory

[Luis Ibanez]

Hi Lars,


A couple of basic questions:


1) How big are your images ?

    How many pixels along every direction ?
    (for both the Fixed and Moving images)


2) How much RAM do you have in your computer ?


Please let us know,


   Thanks


      Luis
