I followed step by step the instalation process of ROMS Plotting Package but when i run the idt gmeta the graph is empty.
Below is a image of what is showing.
So what do you thing that can be happening

Re: plotting upwelling problems
Hi,
A couple things are happening here. First is the fact that your PMIN and PMAX values are way out of range. If you look at the output from the ccnt command you will see from the last frame that the values are between ~14.61 and ~15.97. I would suggest using 14 and 16 instead of -2.0 and 28. These numbers should change depending on the depth you're plotting but 14 and 16 seem reasonable for 100m. Even with values of 14 and 16 you probably won't see much detail on the first frame since the upwelling problem starts with uniformly stratified temperature.
The second issue is that the gebco1 palette is configured to specify exact contour mapping for each color. That is why you see values like -5000 on the color bar. I would suggest using a different palette; perhaps natlan1.pal. The other option is to change the behavior of the gebco1 palette by opening gebco1.pal and changing the 3 in the first line to a 1 so it reads 24 1 1 instead of 24 3 1. This changes IPAL to 1 so it doesn't use the contour mapping in the 8th column.
