Re: Why i can not use the color table of "BlueYellowRed"?

Hi Lin,

It looks like you are using your own personal "ncl", but NCARG_ROOT is pointing to some system NCL installation.

You have NCARG_ROOT set to /usr/local/ncarg, but you are using an "ncl" executable that's installed in your own personal ~/bin directory.

My guess is that the NCL software that's installed in /usr/local/ncarg is version 5.2.1 or earlier, and since this is what NCARG_ROOT is pointing to, it can't find the BlueYellowRed colormap.

If you installed NCL V6.0.0 to your own directory, then you need to set the NCARG_ROOT environment variable to "~/" instead of "/usr/local/ncarg".

If you only have the "ncl" 6.0.0 executable, and not the full software in your home directory, then you can download the BlueYellowRed colormap yourself. See

http://www.ncl.ucar.edu/prev_releases.shtml#NewColorTables6.0.0

for more information.
