[gmx-users] how to make index of a micelle

[Giuseppe R Del Sorbo]

Dear all,

In my simulation I have a lysine + micelle of SDS.

In the analysis, I want to find the spherical radial distribution 
functions of methyl groups around the center of mass of the micelle.

I Know how to make the index for the methyl group, but how can I make an 
index for the micelle?

Thanks a lot

Giuseppe
