Hi all,

I'm trying to simulate a system of POPC- Protein- Water- Ion following the Justin's tutorial of Kalp15-DPPC.

I get the system-solved-ion.gro and run energy minimization. I saw some water molecules in em.gro file, therefore, I erase them and then again save the .gro file as a new one.
But when I make a new index file, updated the top file and then go through the NVT simulation, I get this fatal error:

Warning: atom name 33908 in topol.top and em.gro does not match (HW2 - HW1)
Warning: atom name 33909 in topol.top and em.gro does not match (OW - HW2)
Warning: atom name 33910 in topol.top and em.gro does not match (HW1 - OW)
(more than 20 non-matching atom names)

WARNING 1 [file topol.top, line 57]:
  43770 non-matching atom names
  atom names from topol.top will be used
  atom names from em.gro will be ignored


Setting gen_seed to 2957
Velocities were taken from a Maxwell distribution at 310 K
