      I have two systems. One containing only water and the other one
contains protein and water. Using g_select I made water in 1st solvation
shell but the use of g_hydorder I cannot understand. I read the disscussion
so far disscussed. For these two systems which index I need to choose,
water or OW? What is the use of sgang1 and sgang2? Any suggestion
is appreciated.
Thanks and regards
