Dear all and Justin...

I am trying to do membrane protein simulation by following justin's tutorial
using gromacs 4.5.3 version.  I selected ffG53a6 force field and pasted the
content of lipid.itp file to the corresponding files as per the instructions
in the tutorial but i got error (Fatal error: Atomtype CA not found) while
running grompp command.
I tried some other options by selecting different forcefields but the
problem persist. I think gromacs is not accepting the file after
modifications.  Please kindly help me in this regard...
