        Applying projection after sub-selecting a set of channels that
        were originally used to compute the original projection vectors

        This function will re-normalize projectors to use only the
        remaining channels, thus avoiding that warning. Only use this
        function if you're confident that the projection vectors still
        adequately capture the original signal of interest.
