Hi all

I'm using g_rdf tool in my system with the option -xy, in order to  
calculate a cylindrical distribution function. I read the manual and  
also the help of the tool but I can't find anything about the  
normalization of this particular result. Could anyone tell me how rdf  
tool manages the normalization with the option (-xy). I have a long  
fiber of synthetic polymer, oriented along z direction, and I want to  
calculate the cylindrical distrib. function from the center of it  
(backbone). The rdf (cylindrical) shows some peaks which decay to zero  
at long distances, so I don't understand how the normalization is done.

Thank youn in advance
