HBONDS commands enable you to manipulate the list of hydrogen bonds. If you want to display them, you have to bare in mind that the macro 're_image.cmds' is the place to govern presentation of hydrogen bonds on a display.
They are useful during minimization as they preserve as well as enforce (regular) hydrogen bonding patterns.
The macro is loaded using MAIN_CMDS:load_hbonds.com.
HBON_WORK calculates the list of hydrogen bonds for the "WORK_SEGM" list of segmnet IDs.
HBON_WORK calculates the list of hydrogen bonds for the "WORK_SEGM" list of segmnet IDs.
HBO_MAIN calculates the list of hydrogen bonds for the main chain atoms of the "WORK_SEGM" list of segment IDs.
HBON_DEL deletes the hydrogen bond between the two last picked atoms.
HBON_INI initializes the hydrogen bond list by deleting all hydrogen bonds.
