Re: contour or shade vertical section with bottom line along theoceancruise

[Namba Takaya <takayanamba@xxxxxxxxxxx>]

Dear Dr. Ansley Manke

Thank you for your kind and quick help.

I made it (etopo60,or etopo20) but 
When I use the etopo5 and set the rather wide region,
the insufficient memory error come.

I did
when I start ferret, 
>ferret -memsize 10 (even larger than 10)
and 
set memory/size=10 (even larger than 10)

it dose not work.

Then I make the region smaller, next
error come like
a program limit has been reached, xxxxxx
  plot size is : xxxxxxxxx.

Could I overcome this problem in ferret?
Is this  because of the  memory limitation of Ferret?
One way we use the smaller region or coarse topo file?

Thank you in advance.
