how to define axis-files? (modified)

[Yang Kun <yangk@xxxxxxxxxxxxxx>]

Dear ferreters,

I want to use "define axis/file=  "to define an irregular
axis in z axis. 

The depth in my model is as below:

  lev   = 25.0, 81.25, 156.25, 275.0, 462.5, 712.5,
          1175.0, 2000.0, 3000.0, 4000.0, 5500.0;

So i generate a TMAP grid file to describe the details.
The file "zdepth.grd" is as below, but it has some problems.
When i use it in ferret, the result is:
 
  **TMAP ERR: error in line definition
               Coord at (i) less than coord at (i-1). LINENAME=ZAXIS

I don't know what's wrong in it. Anyone can help me?

Thanks a lot!
yours,
Kun Yang

"zdepth.grd"
