[gradsusr] Do the GrADS Examples work?

The last try was my mistake. I have several installation of GrADS and OpenGrADS. On the OpenGrADS machines it default to that, so I just tried it on a machine with only GrADS, but the same result. I downloaded the binary for Linux, so there was no compilation. It is encouraging to note that the tutorial works. As I said, I am just trying to verify my install before I turn it over to the user. Thanks.

For what it's worth, I had my Graduate level class go through the entire tutorial seamlessly less than 1 month ago.
May I recommend that you simply start over from scratch (i.e., redownload, compile, etc.). I had some issues yesterday downloading modules from NCAR/RAL (I know, not GrADS-related) that didn't build properly - and the reason why it didn't work made no sense. We downloaded again, built from scratch, and like magic, things worked out.
thank you,
matei

Therefore it the tutorial is not working, and you are absolutely sure you can't open the tutorial file itself, and not mistaking the path or anything, I would say you have a faulty installation.
