Dear Amber Users and Developers,
                                                               I am going
to simulate a CNT functionalized with HIP by AMBER12 using ff12SB. I have a
off file of it. After loading the off file and pdb file of my system I
solvate it by about 5000 TIP3P water molecules. Then add one Cl- ion to
neutralize the system. Now when I am going to make prmtop and inpcrd file,I
am getting following warnings.

 But I have got a prmtop and inpcrd file. So, can I proceed with these
files or do I have to check something?
