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?
