[AMBER] How does radial work?

Dear All,

I was calculating the radial distribution function of :WAT.O using the
following command:

/radial rdf_005 0.1 10 :WAT.O :36 closest noimage
.../

the results show the smallest distance is around 1.550, less than the
VDW radius of OW. And :36 is SER, in which the VDW radius of atoms is at
least 1.3870. How can a oxygen atom be so close to an atom that the
distance between them is half the sum of their VDW radius? What did I
misunderstand here?

Best regards
Alan
