Hi Kim,
If you have the depths available in a Ferret variable (i.e if you could type
yes? LIST my_depths
and see your depths) then you can use this technique:
DEFINE AXIS/DEPTH/FROM_DATA/NAME=LDEOdepths/Z/units=meters my_depths
LET my_temp = temp[gz=my_depths@asn]
Now use my_temp instead of temp -- my_temp will be based on the Z axis of
irregular depths.
