[gmx-users] only three options for genrestr

[reisingere at rostlab.informatik.tu-muenchen.de]

Hi everybody,
I wanted to fix the whole protein with "genrestr" so that only the water
molecules are flexible. I already did this once and there I had about 13
options what I want to fix so that I could select "protein"
But now I only have 3 options what I can fix: System, Water, SOL.
The only difference to the first time I used it is that now there is a
layer of dummy atoms around my protein simulating the membrane.
So my question is: How can I now only fix the protein and not the whole
system.
Thanks, Eva
