Re: Removing missing values from a 3D array

The original post is not clear.

What procedure are you using to output the ascii file.
Is the source grid rectilinear or curvilinear?

One scenario: If you have a rectilinear array x(lat,lon):

      asciiwrite("foo.txt", x(jStrt:jLast,iStrt:iLast) )

      opt = True
      opt@fout = "foo.txt"
      write_matrix( x(jStrt:jLast,iStrt:iLast) , "10f7.2", opt)

Please see examples at:
