[gmx-users] DNA topology error

[maria khan]

dear Mark Abraham

According to my error like  """Residue 9 named DG of a molecule in the
input file was mapped to an entry in the topology database, but the atom
O5' used in that entry is not found in the input file. Perhaps your atom
and/or residue naming needs to be fixed."""

if O5' can be set in pdb manually,then how  the other values of
cordinates   (figures) can be provided manually,as these values are
experimental.

Thanks.

Maria.
