[gmx-users] How to ignore hydrogen of one part of a pdb file by pdb2gmx

[柯谱]

Hello,

             I have a pdb file that contains a transmembrane protein.  
The protein needs to be treated by -ignh directive of pdb2gmx while the 
lipids do not(and can not, since there is no hdb file for lipids).  How 
can I process the structure without going through the insertion of the 
protein again?   Thanks!
                             Best wishes,
                                     Pu,
