Hi all,

I am trying to compute the pairwise rdf for the O and nearby water using the
these commands.

trajin data-0.00.crd
image origin center
radial rdf0.00o2thfwater 0.05 10.00 :WAT.H* :THF.O2 closest density 0.033456
radial rdf0.00o1thfwater 0.05 10.00 :WAT.H* :THF.O1 closest density 0.033456
radial rdf0.00oe2thfwater 0.05 10.00 :WAT.H* :THF.OE2 closest density
0.033456
radial rdf0.00oe1thfwater 0.05 10.00 :WAT.H* :THF.OE1 closest density
0.033456
go


However when I look at the carnal or standard.xmgr i see that rdf doesnot
converge to a value of 1.
Could you help me how I could rectify this. Do I need to specify a volume or
change the density number.

thanks,

ganesh
