DESCRIPTION

    "group" creates or updates a group object: a container for
    organizing objects into a hierarchy.
    
USAGE

    group name [, members [, action ]]

ARGUMENTS

    name = string: name of the group

    members = string: space-separated list of objects to include in
              the group

    action = add, remove, open, close, toggle, auto, ungroup, empty,
             purge, excise

EXAMPLE

    group kinases, 1oky 1pkg 1t46 1uwh 1z5m
    group kinases, open
    group kinases, close

NOTES

    Group objects can typically be used as arguments to commands.  In
    such cases, the command should be applied to all members of the
    group.  If the group is used as a selection, then all atoms in all
    objects in the group should be included in the selection.

    When a group objects is open, objects can be added or removed from
    the group by right-clicking and dragging in the control panel.

DESCRIPTION

USAGE

    ramp_new name, map_name [, range [, color [, state [, selection [,
        beyond [, within [, sigma [, zero ]]]]]]]]

ARGUMENTS

    name = string: name of the ramp object

    map_name = string: name of the map (for potential) or molecular
    object (for proximity)
    
    range = list: values corresponding to slots in the ramp

    color = list: colors corresponding to slots in the ramp

    state = integer: state identifier

    selection = selection: for automatic ranging
    
    beyond = number: with automatic ranging, are we excluding
    values beyond a certain distance from the selection?

    within = number: with automatic ranging, are we only including
    valuess within a certain distance from the selection?

    sigma = number: with automatic ranging, how many standard
    deviations from the mean do we go?

    zero = integer: with automatic ranging, do we force the central
    value to be zero?

EXAMPLES

    ramp_new e_pot_color, e_pot_map, [-10,0,10], [red,white,blue]

NOTES

    Color ramps are extremely powerful but complicated to use.

    In the simplest case, they can be used to color representations
    based on the potential values found in a map object at the
    corresponding positions in space.

    In another simple case, representations can be colored based on
    proximity to a target.  Note that since ramp targets must
    themselves be real objects (not merely selections), the "create"
    command may be needed in order to generate an appropriate target.
    
    In more complicated cases, they can be used to color
    representations on one object based atoms found in another.

    Ramps can operate recursively.  In other words, the output color
    from one ramp can be used as the input color for another.  For
    example, you could color by map potential within a certain
    distance of the target object, beyond which, a uniform color is applied.
