[MINC-users] mincreshape - "Can't allocate 135168 bytes"

[Soren Christensen]

Hi,
 I am gettign a strange error from mincreshape when downsampling a dataset.
This is what I have:
>mincinfo T320.mnc
file: T320.mnc
image: signed__ short -2048 to 3062
image dimensions: time zspace yspace xspace
    dimension name         length         step        start
    --------------         ------         ----        -----
    time                       12            1            0
    zspace                    320          0.5      -539.75
    yspace                    512       -0.461      107.894
    xspace                    512       -0.461      117.894

And I do:
>mincreshape -clobber -dimsize xspace=128 -dimsize yspace=128 -dimsize
zspace=128 T320.mnc t.mnc
Copying chunks:.(from miicv_get): Can't allocate 135168 bytes
(and I have several gigs of RAM free)

But it works with 16 slices:
>mincreshape -clobber -dimsize xspace=128 -dimsize yspace=128 -dimsize
zspace=16 T320.mnc t.mnc
(OK)

Googling "Can't allocate 135168 bytes" leads to some results, but not
nothing that is an obvious fix to me.
