Pls can anyone offer my a step-by-step guide to install grads on my laptop (ubuntu linux). I have tried all possible options including the opengrads/COLA and "sudo apt-get install grads". The latter is able to have grads installed but am unable to read any files after grads is installed this way.
Thanks in advance,
Hyacinth
