# PREREQUISITES:
#
# You must use moltemplate.sh to create 3 files:
# system.data system.in.init system.in.settings
# (Follow the instructions in README_setup.sh, or run it using ./README_sh.)
#
# -------- REQUIREMENTS: ---------
# 1) This example requires the "USER-MISC" package. (Use "make yes-USER-MISC")
# http://lammps.sandia.gov/doc/Section_start.html#start_3
# 2) It also may require additional features and bug fixes for LAMMPS.
# So, after typing "make yes-user-misc" in to the shell, ...
# be sure to download and copy the "additional_lammps_code" from
# http://moltemplate.org (upper-left corner menu)
# 3) Unpack it
# 4) copy the .cpp and .h files to the src folding of your lammps installation.
# 5) Compile LAMMPS.
#
# If LAMMPS complains about an "Invalid pair_style", or "Invalid dihedral_style"
# then you made a mistake in the instructions above.

# Note: The temperature 300.0 K corresponds to 0.907033536873*epsilon
# (for the "epsilon" used by the coarse-grained lipid), and
# to 0.33*epsilon (for the "epsilon" used in the coarse-grained protein)
# Note: The langevin damping parameter "120" corresponds to
# the 0.12ps damping time used in Watson et. al JCP 2011.
# Note: We maintain the system system at constant (zero) tention
# using a barostat damping parameter Pdamp=1000 ("0 0 1000")
# optional (not sure if this helps):
