i.fft and i.ifft in Linux

GRASS community-

  It seems that my i.fft and i.ifft are not working on my Linux
machine. I am getting a "G_malloc out of memory" error when I try to run
them.

Hi,

today I had a similar problem. I fixed it clearing my /tmp directory...

That should be all - your /tmp might be to small. Some temp.files
are also created in your grass_database. i.fft etc. are very
space consuming depending on the size of your raster image.

Hope this helps

PS: Try the new Linux GRASS 4.2.1 binaries if you like.

Markus-

Thanks for the information. It seems that it was indeed some kind of
system limitation and not a problem with GRASS.

Thanks again.
