[gmx-users] H-atoms in .hdb file

[Shima Arasteh]

I added the FOR residue as protein in residuetypes.dat file, but still says it's not identified as protein/DNA/RNA. 

Would you mind helping me with your suggestions?

Thanks in advance

 
Sincerely,
Shima

"Dangling bond" errors were introduced as part of the output in Gromacs 4.5. The "aminoacids.dat" file was only used by older (4.0.x and earlier) versions of Gromacs.  You need to be modifying "residuetypes.dat" to indicate that FOR is a Protein residue so that the chain is continuous with respect to its content type.
