[gmx-users] gmx solvate

[Alexander Alexander]

Dear gromacs user,

As you know, the "gmx solvate" can be used as below to merge two gro files
which have an identical box size;

gmx solvate -cp A.gro -cs BC.gro -o ABC.gro

The A.gro contains only the "A" molecules serving as solute while BC.gro
contains two types of B and C molecules serving as the solvent.

Usually, some of the solvent atoms are removed (either B or C or both of
them) from the final ABC.gro file because of overlapping.
My question is that how I can  enforce the program to remove only from one
of the species (for example, B , not from C) if something want to be
removed?

Thanks,
cheers,
Alex
