[gmx-users] trjconv to remove periodicity (KALP15 in DPPC tutorial)

[Atila Petrosian]

Dear Justin

I do your tutorial entitled " KALP15 in DPPC ".

In Step Three: Defining the Unit Cell & Adding Solvent,

You said "Use trjconv to remove periodicity ".

When I use trjconv -s em.tpr -f dppc128.gro -o dppc128_whole.gro -pbc mol
-ur compact,
gromacs tell me: Select group for output.

Which group I should select? system or dppc?


Best wishes
