    "Performs a striped (banded) Smith Waterman Alignment.\n\n    First a StripedSmithWaterman object must be instantiated with a query\n    sequence. The resulting object is then callable with a target sequence and\n    may be reused on a large collection of target sequences.\n\n    Parameters\n    ----------\n    query_sequence : string\n        The query sequence, this may be upper or lowercase from the set of\n        {A, C, G, T, N} (nucleotide) or from the set of\n        {A, R, N, D, C, Q, E, G, H, I, L, K, M, F, P, S, T, W, Y, V, B, Z, X, *\n        } (protein)\n    gap_open_penalty : int, optional\n        The penalty applied to creating a gap in the alignment. This CANNOT\n        be 0.\n        Default is 5.\n    gap_extend_penalty : int, optional\n        The penalty applied to extending a gap in the alignment. This CANNOT\n        be 0.\n        Default is 2.\n    score_size : int, optional\n        If your estimated best alignment score is < 255 this should be 0.\n        If your estimated best alignment score is >= 255, this should be 1.\n        If you don't know, this should be 2.\n        Default is 2.\n    mask_length : int, optional\n        The distance between the optimal and suboptimal alignment ending\n        position >= mask_length. We suggest to use len(query_sequence)/2, if\n        you don't have special concerns.\n        Detailed description of mask_length: After locating the optimal\n        alignment ending position, the suboptimal alignment score can be\n        heuristically found by checking the second largest score in the array\n        that contains the maximal score of each column of the SW matrix. In\n        order to avoid picking the scores that belong to the alignments\n        sharing the partial best alignment, SSW C library masks the reference\n        loci nearby (mask length = mask_length) the best alignment ending\n        position and locates the second largest score from the unmasked\n        elements.\n        Default is 15.\n    mask_auto : bool, optional\n        This will automatically set the used mask length to be\n        max(int(len(`query_sequence`)/2), `mask_length`).\n        Default is True.\n    score_only : bool, optional\n        This will prevent the best alignment beginning positions (BABP) and the\n        cigar from being returned as a result. This overrides any setting on\n        `score_filter`, `distance_filter`, and `override_skip_babp`. It has the\n        highest precedence.\n        Default is False.\n    score_filter : int, optional\n        If set, this will prevent the cigar and best alignment beginning\n        positions (BABP) from being returned if the optimal alignment score is\n        less than `score_filter` saving some time computationally. This filter\n        may be overridden by `score_only` (prevents BABP and cigar, regardless\n        of other arguments), `distance_filter` (may prevent cigar, but will\n        cause BABP to be calculated), and `override_skip_babp` (will ensure\n        BABP) returned.\n        Default is None.\n    distance_filter : int, optional\n        If set, this will prevent the cigar from being returned if the length\n        of the `query_sequence` or the `target_sequence` is less than\n        `distance_filter` saving some time computationally. The results of\n        this filter may be overridden by `score_only` (prevents BABP and cigar,\n        regardless of other arguments), and `score_filter` (may prevent cigar).\n        `override_skip_babp` has no effect with this filter applied, as BABP\n        must be calculated to perform the filter.\n        Default is None.\n    override_skip_babp : bool, optional\n        When True, the best alignment beginning positions (BABP) will always be\n        returned unless `score_only` is set to True.\n        Default is False.\n    protein : bool, optional\n        When True, the `query_sequence` and `target_sequence` will be read as\n        protein sequence. When False, the `query_sequence` and\n        `target_sequence` will be read as nucleotide sequence. If True, a\n        `substitution_matrix` must be supplied.\n        Default is False.\n    match_score : int, optional\n        When using a nucleotide sequence, the match_score is the score added\n        when a match occurs. This is ignored if `substitution_matrix` is\n        provided.\n        Default is 2.\n    mismatch_score : int, optional\n        When using a nucleotide sequence, the mismatch is the score subtracted\n        when a mismatch occurs. This should be a negative integer.\n        This is ignored if `substitution_matrix` is provided.\n        Default is -3.\n    substitution_matrix : 2D dict, optional\n        Provides the score for each possible substitution of sequence\n        characters. This may be used for protein or nucleotide sequences. The\n        entire set of possible combinations for the relevant sequence type MUST\n        be enumerated in the dict of dicts. This will override `match_score`\n        and `mismatch_score`. Required when `protein` is True.\n        Default is None.\n    suppress_sequences : bool, optional\n        If True, the query and target sequences will not be returned for\n        convenience.\n        Default is False.\n    zero_index : bool, optional\n        If True, all inidices will start at 0. If False, all inidices will\n        start at 1.\n        Default is True.\n\n    Notes\n    -----\n    This is a wrapper for the SSW package [1]_.\n\n    `mask_length` has to be >= 15, otherwise the suboptimal alignment\n    information will NOT be returned.\n\n    `match_score` is a positive integer and `mismatch_score` is a negative\n    integer.\n\n    `match_score` and `mismatch_score` are only meaningful in the context of\n    nucleotide sequences.\n\n    A substitution matrix must be provided when working with protein sequences.\n\n    References\n    ----------\n    ..
