Hello Parthiban,
Can you elaborate more on the 'wrong answer'?
Perhaps the following link can shed some light on the 'wrong' answer:

Quoting parthi...@ncbs.res.in:
Hello,
Can anyone tell, how to index two specific atoms, (one form protein and
one from ligand)
eg; 440th atom of protein & 450th atom of small molecule or OED of small
molecule.
The format of the index files is simple. You can easily write a script
to accomplish waht you want, or even do it manually. First you need to
add the name of the index group,
[ the_name ]
Then follows the list of atoms belonging to the group. If you want the
440h atom of the protein, then just write 440 plus the number of the
first atom in the protein. So if your protein starts at atom no 123,
then its 440 atom will be number 563. Your index group will look
something like this:
[ the_440th_protein_atom ]
563
This you can do with the text editor of your choice. Simple as that.

My second question is:
how to calculate the distance b/w these two atoms.
i tried g_dist by including the indexed file with this, but the graph
displays a wrong answer.
thanks
In advance.
Parthiban.
