[gmx-users] No default bond types

[Neena Susan Eappen]

Hi Justin,

Yes errors from grompp are very clear. Initially, I had errors for all four 4 new bond and 9 new angle types, grompp specifically stated which line in the topology file was missing. Accordingly, I added parameters for all in the ffbonded.itp file correctly. Even after that, I still wonder why I have errors....

Hi Alessandra,

For the 4 new bond types and 9 new angle types, I modified the ffbonded.itp file. However, the command grompp gave error for one bond and 6 angle types although I have all in there. Is there a way to resolve this?

Hello gromacs users,

I just modified opls force field for a modified aminoacid with 4 new bond types and 9 new angle types. However, the command grompp gave a no default error for one bond and 6 angle types. Is there a way to resolve this?

Many thanks and Take care,
Neena
