[gmx-users] Dangling bond error for dna

[majid hasan]

Dear All,

I created .pdb file for dna using gabedit. But when I try to create the topology 
file I get this error: Fatal error:
There is a dangling bond at at least one of the terminal ends and the force 
field does not provide terminal entries or files. Edit a .n.tdb and/or .c.tdb 
file.

Output of pdb2gmx, and my input pdb files are attached. Could anyone please 
suggest why this is happening?

Thanks,
Majid
