Convert GULP potential to lammps useable potential

Hello, I have the output file from GULP. But I want to use this in LAMMPS. Is there a way I can convert it to a lammps useable potential? Or can I generate a file that can be used by lammps?

The only way to use the output file of most programs as an input for another code is to cut and paste the relevant information to your new input file. GULP has some capability to write out things in LAMMPS format - see the output option in the help text. However, this shouldn’t be relied upon to do the whole job as you need to check and modified from this starting point to ensure that things are correct.
