[gmx-users] How to remove water from lipid bilayer core

[Anirban Ghosh]

Hi ALL,

I have a built a system of protein embeded in lipid bilayer and solvated it according to the GROMACS membrane simulation tutorial. I want to delete a few water molecules that are there in the hydrophobic core of the bilayer. I deleted them manually from the .gro file and corrected the atom numbers, but still getting an error:
-----------------------------------------------------------------
Invalid line in prt_genbox_MOD.gro for atom 73510:
  10.81119  10.81119  10.01306
-----------------------------------------------------------------

How can I modify the last line and get a correct .gro file by removing the unwanted waters? In the tutorial it is stated that there are some scripts to remove the unwanted waters. Can anyone provide me such a script.
Any suggestion is welcome.
