# You can use packmol to create a file containing the atomic coordinates
# for a system of coarse-grained lipids mixed with water using this command:



packmol < mix_lipids+water.inp




# If it takes too long for packmol to run, try lowering the "tolerance"
# parameter by editing the "mix_lipids+water.inp" file.






#      NOTE:
# It is not necessary to use an external coordinate-generation 
# program like PACKMOL to mix different kinds of molecules together. 
# (You can usually accomplish the same thing using moltemplate "move()" commands
#  See the "3bodyWater+hydrocarbons" example.  You can also create random 
#  arrays using the "new random()" command. See the "membrane+protein" example.)
#
# However PACKMOL does a good job, and is especially convenient when you have
# a large disparity between the sizes of the molecules in the system
# (such as a protein surrounded by water, for example).
