Hi,

I do not know. After running pdb2gmx I am not getting the .itp file for
the DC5... I am using gromacs 5.0.4. What can be wrong here?


Did you check the .rtp for DC5, as Mark suggested? Based on your knowledge of DNA structure, why might there be an issue with a 5'-phosphorus atom?

Hi,

What name does the .rtp entry for DC5 use for its phosphorus atom?

Dear gmx users,

After running a pdb2gmx script of the pdb file I am getting an error
message:


Fatal error:
Atom P in residue DC 2 was not found in rtp entry DC5 with 28 atoms
while sorting atoms.


The DC 2 in pdb file:

TER   11412      LEU B 366

What can be wrong with the P atom?

Thanks for any suggestions.
