Hi Justin, Thanks for your reply. As you guessed correctly, for making a topology file I used "g_x2top -f file.gro -o file.top -ff forcefield -noparam". I have a CNT system and I thought I should use g_x2top instead of pdb2gmx command. If I'm right, what may cause this error and what would be the solution? Thanks!
