[Insight-users] generating a vector Image

[Hila Hiler]

Dear David,

many thanks for your effort to help.

I found the problem: a large amount of memory space was required to
generate about 100*3MB for a vector image(100MB for an image (pixeltype of
double) and multiply by three for three vector length) .
I use a laptop and maybe it was a problem.
so I simply cropped my input image to 60MB and the final size was ~180MB
for a vector image.

if you have something in mind to sharp my observation- please mention it
... I have to change a computer?
any information would be very appreciated!

Best Regards,
Hila
