The input file for adding solvent is the output file from the editconf command.

At this point, the workflow is just like any other MD simulation. .
edu advanced-cyberinfrastructure). First, we need a basic TPR file (an empty file is sufficient, just ignore the warnings that gmx grompp spits out by setting -maxwarn 10), then run gmx genion (which has convenient options to neutralize the system and set the concentration (check the help); gmx genion also.
For the purpose of this tutorial, we will use the rhombic dodecahedron, as its volume is 71 of the cubic box of the same periodic distance, thus saving on the number of water molecules that need to be added to solvate the protein.
There are two steps to defining the box and filling it with solvent Define the box dimensions using the editconf module. thank you for replying I did as you suggested solvating my protein with the following command gmx solvate -cp proteinprocessed. top In the above the soluteprotein's coordinates are initially stored in conf. This is the same.
. Official GROMACS. First, calculations can be done either in single precision (recommended for most purposes) or double precision (only necessary for precise.
