[gmx-users] Fatal error: Atomtype CA not found

2017-03-02 Thread Puneet
Hi, 

 

I am performing Membrane protein simulation by using Bevan Tutorial "KALP15
in DPPC" with example given in tutorial. I have made steps upto "To use
parameters in lipid.itp, we will have to make some changes to our
pre-packaged gromos53a6.ff/forcefield.itp. Make a new directory in your
working directory called "gromos53a6_lipid.ff" and copy the following files
from gromos53a6.ff into it" and kept all the files in gromos53a6_lipid.ff
directory as mention under this section. I have also made all the required
changes in "ffnonbonded.itp & topol.top" as mention in the tutorial and
taken minim.mdp & topol_dppc.top files from link given in the tutorial. But
on step "Orient the protein and membrane" when I run 

 

Command: grompp -f minim.mdp -c dppc128.gro -p topol_dppc.top -o em.tpr

 
I got  Fatal error: Atomtype CA not found

Can u please suggest me how to resolve this error.


Thanks in Advance!


Regards!


Puneet

This is a unix/linux problem, not a gromacs problem.
And as such, I strongly suggest that you not run such commands as root, but
rather as an ordinary user.
Running commands as root, especially if you know little or no unix/linux can
be very dangerous.
The problem is probably in your path.  The shell needs to know where the gmx
executable is located.
There are several linux approaches to that, but for now, find out where gmx
is installed, and do the following:
export GMXDIR="location of gmx executable"
source $GMXDIR/GMXRC 

Then it should work.

Peter Stern
