我明白了,十分感谢!我之前用的pdb含了几百个lipid,所以出错了。 现在我换成了只含一个lipid 的pdb,但是发现了另一个问题,这是我的input文件:
#
# Lipid double layer with water above and below
#
tolerance 2.0
filetype pdb
output bilayer.pdb
#first layer of water
structure water.pdb
number 2000
inside box 0. 0. 0. 72. 72. 25
end structure
#second layer of water
structure water.pdb
number 2000
inside cube 0. 0. 75. 72. 72. 100.
end structure
structure POPG.pdb
number 127
inside box 0. 0. 20. 70. 70. 50.
atoms 67
below plane 0. 0. 1. 25.
end atoms
atoms 1
over plane 0. 0. 1. 48.
end atoms
end structure
structure POPC.pdb
number 134
inside box 0. 0. 20. 70. 70. 50.
atoms 70
below plane 0. 0. 1. 25.
end atoms
atoms 1
above plane 0. 0. 1. 48.
end atoms
end structure
但是一直报错:ERROR: Packmol was unable to put the molecules in the desired regions even without
considering distance tolerances.
Probably there is something wrong with
the constraints, since it seems that
the molecules cannot satisfy them at
at all.
Please check the spatial constraints and
try again.
>The maximum number of cycles ( 80 ) was achieved.
You may try increasing it with the nloop0 keyword, as in: nloop0 1000
拜托指教 感谢!!
