You process it like any other file.  If you have protonation states that differ 
from pdb2gmx's assumptions (it assumes protonation states based on pH 7 and 
histidine protonation based on H-bonding networks), then you can set the 
appropriate forms using the appropriate command-line flags (-inter will prompt 
you to choose the protonation state of every single titratable residue, but 
depending on what you need to set, that may be overkill).
