I want to use the creat atoms tool of lammps. I am running lammps on ubuntu 11.04, I first compile the fortron file using gfortron-4.5 and get the executable file “a.out”
then i try to run the command
./a.out<file.input
a string “Killed” appear with no resulting file and execution stops.

Kindly guaid me about the issue.
