    Use g_rms with a suitable index group.

I am not able to search some relevant document about creating index group fro g_rms ... I found one i gromacs website http://www.gromacs.org/Documentation/How-tos/Making_Commands_Non-Interactive but this link doesnot explain much about it ... can u pls guide me to some relevant link ??

See the manual, section 8.1 and appendix D.83. If you search the Gromacs site for "index group" you will find (among others):

I am stating my question here again : I want to calculate the rmsd of amino acid 65 to 67 of two simulated proteins with loop replacement in another one to find out how the position of these 3 amino acids change due to the replacement of a loop region in same protein ... How can I achieve it with gromacs...
