Hi All,
I ran into a problem when running the methanol example in "Getting Started". When I ran "grompp -v", I got the following: Fatal error:
  Atomtype CMET not found

I installed Gromacs 4.5.3 on Ubuntu and planned to learn the software. Now I am stuck. Many thanks for your help! I really appreciate it.


There is a typo in the methanol.itp file in the /tutor/methanol subdirectory. Replace it with the one from the gromos43a1.ff directory. There may be more errors along the way; I don't think the demo has been updated in some time.

        Hi All,
        I am a new user of Gromacs and Linux. I am using Ubuntu 10.10
        and installed Gromacs 4.5.3 following the instructions. When I
        ran the demo, I found that when I pressed <enter>, the xterm
        window which is supposed to appear separately just flashed and
        disappeared immediately. For instance, "the output of the genbox
        program should appear in a separate xterm window", but when I
        pressed <enter> the window flashed and disappeared immediately.
        Is there anything wrong that I need to fix or is that the way it
        should be?


    It is possible that something is wrong with the demo, but more
    likely something is wrong with your X window settings.  If you're
    looking for tutorial material, there are far better resources than
    this simple walkthrough:
