[gmx-users] grompp error : Atomtype CAro not found

2020-03-02 Thread Atila Petrosian
Dear Justin and Dallas, Thanks for your answers. I am so confused. I am beginner in MD simulation of lipid + small molecule. '' There are far better options for lipids than the old Berger parameters used in the tutorial. I wrote the tutorial in 2008 and it reflected a common protocol at the time

You need to use the same forcefield. Since you are using ATB to generate the topology for your small molecule, then it stands to reason that you then should use ATB for the lipid molecule. Search ATB, I'm pretty sure the various lipids will already be there, and suspect they will be some that
