[gmx-users] generating martini-version of lipids

[jagannath mondal]

Hi Tsjerk
  Thanks for your response. I was mainly looking for converting a dppg
bilayer in charm36 format into a coarse-grained one. However, the "Mapping"
folder does not have any mapping for dppg lipids. Is there any specific
suggestion regarding this?
