Re: PDF error: error opening output file

Hi Donna,
Whenever you get a warning that looks like this:

warning:GKS:GOPWK: --PDF error: error opening output file
fatal:Workstation with PID#8 is not open
fatal:Unable to open Workstation-Can't Create

It means that NCL was unable to open the output file for writing, either
due to the directory/path being invalid or because you don't have
permissions to write to that file or over that file.

Thus, I would guess that within your gsn_open_wks call you are
specifying a directory that isn't present on your mac, or a directory
that you do not have permission to write to, or the file is already
there and you don't have permissions to overwrite it.

Hope that helps! Adam
