# Add Missing Hydrogens

Add missing hydrogen atoms?

Add hydrogens appropriate for pH

Add membrane and water

The membrane will lie in the XY plane and be centered at Z=0. Make sure the protein is properly oriented and positioned. When possible, it is easiest to use a PDB file from OPM since they are already properly positioned.

Minimum padding around protein: (nm)

Ions will be added to neutralize the model. You can optionally add more ions based on a desired bulk ionic strength.
