SET BAD

        LAS\SET BAD Check

    Specify the way the commands which have to mix channels  behave  in  the
    case of bad channels. There are two families of such commands:
      -  resampling (part of) commands: RESAMPLE, and optionally ACCUMULATE,
        AVERAGE, and STITCH if resampling is needed,
      - addition (part of) commands: ACCUMULATE, AVERAGE, and STITCH.

    Check may be OR or AND. Default is OR, i.e. the output channel is bad if
    any  of  the input channels is bad. AND indicates to use all the non-bad
    channels (if any) to compute the output channel.
