[Camino-users] Problem Converting DWI Data

[Michael Dayan]

Hi Maedeh,

You are running out of memory. You have to increase it by changing the
maximum value with the following command:

export CAMINO_HEAP_SIZE=2000

where 2000 = 2000 Mb and can be set to whatever maximum amount of RAM you
want Camino to use (within the amount of RAM you have obviously).

You can do it as a one off by typing this command in your terminal, or set
it permanently by writing it in your <HOME_DIR>/.bashrc file (for the
changes to take effect you will need to refresh your current terminal with
the new bash settings by typing source ~/.bashrc, or you can just start a
new terminal).

Best,

Michael
