DESCRIPTION

    "feedback" changes the amount of information output by pymol.

USAGE

    feedback action, module, mask

ARGUMENTS

    action = set, enable, or disable

    module = string: a space-separated list of modules or simply "all"

    mask = string: a space-separated list of output categories or simply "everything"

NOTES

    "feedback" alone will print a list of the available module choices

PYMOL API

    cmd.feedback(string action,string module,string mask)

EXAMPLES

    feedback enable, all , debugging
    feedback disable, selector, warnings actions
    feedback enable, main, blather
