[Chimera-users] Add-H to water O

Is it possible with CHIMERA to add-H selectively to O atoms to get H-bonded water molecules? I used REDUCE to add-H (-build flag) but was unable to get H2O from O atoms, although het database is in place. What I am trying to get is a reasonable H-bonded water for a highly hydrated protein, before submitting to MD to actually see h-bonding. thanks francesco pietra
