Hi all,
That sounds like a good solution, to rename the variable so you can always use it easily. If you don't have control over the file, say if the dataset were a remote URL you wouldn't be able to do that, so another means of handling this with Ferret is to rename a variable after opening a file, just for the Ferret session. This would look like this:
yes? use "http://ferret.pmel.noaa.gov/thredds/dodsC/data/PMEL/smith_sandwell_topo_v8_2.nc"and througout the session, Ferret would act as if the name of the variable in the dataset were RELIEF. All of the attributes remain as they were in the original dataset.
yes? sh dat
currently SET data sets:
1> http://ferret.pmel.noaa.gov/thredds/dodsC/data/PMEL/smith_sandwell_topo_v8_2.nc (default)ROSE Topography and Bathymetry ( 81 1:10800 1:6336 ... ...
name title I J K L
yes? set var/name=relief rose
yes? sh dat

name title I J K L

thank you all for your suggestions.
Now, I am using this data.
shade 'Z' performs well but I decided to rename this variable.
Kind regards,

It worked here but with
shade 'Z'
because Z is the variable and z is the title.
