[Insight-users] ImageSeriesReader memory allocation for large datasets

[Luis Ibanez]

Hi Marius,

Are you running this in a Windows 64 bits machine ?

Otherwise, Windows 32 processes can only manage 2Gb of RAM
regardless whether you have more RAM available in your machine.

BTW: you mention the number of slices, and the number of bits
      per pixel, but not the number of pixels per slice.
      Could you please clarify ?


    Thanks


       Luis
