[gmx-users] problem in running tutorial

[ireena bagai]

Dear all,
       I installed gromacs on a linux machine. When
i'm trying to run the "demo" program, it gets
initiated but then upon pressing enter, it doesn't run
any process and simply says "pdb2gmx:command not
found"; "mdrun:command not found"; "grompp:command not
found".
could anyone please suggest the plausible reason for
it?
thanks a lot
regards
ireena.
