[gmx-users] g_density : centering the density distribution plot

[Arneh Babakhani]

Hello, 

I'd like to use g_density to obtain a density distribution plot.  Now, 
I'd like to place the center of that distribution on the zero of the 
horizontal axis.   How do I so using g_density?  From reading the 
manual, I see there's an option, "-center", which should do the trick.  
But I've tried it, and it doesn't work (the result is no different than 
when I don't use this option).   I'm also using "-d Z" (the option to 
make the Z-axis the normal direction).  Any suggestions?
