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

[Baptiste Demoulin]

Hi,

For a system with several component in the membrane, I think that
InflateGRO 2 would be more appropriate. See
http://code.google.com/p/inflategro2/ for the code and the related
publication http://pubs.acs.org/doi/full/10.1021/ci3000453

Bests,

Baptiste
