Hi Prasun,
You probably weren't careful enough when changing the residue names.
It seems the residue names need to be shifted by one position, and
pdb2gmx reads DTHY as TH somehow, matching it to THF based on the
first letters.
The proper sed command for the conversion is:
sed -e '{s/\(^.\{17\}\) DG /\1DGUA/; s/\(^.\{17\}\) DA /\1DADE/;
s/\(^.\{17\}\) DC /\1DCYT/; s/\(^.\{17\}\) DT /\1DTHY/}'
Hope it helps,
Tsjerk
