    From the seqlets object of a TF-MoDISco pattern's seqlets and alignments,

        `seqlets_arr`: a TF-MoDISco pattern's seqlets object array (N-array)
        `one_hot_seqs`: an N x R x 4 array of input sequences, where R is
            the cut centered size

        `true_profs`: an N x T x O x 2 array of true profile counts
        `pred_profs`: an N x T x O x 2 array of predicted profile probabilities
        `pred_coords`: an N x 3 object array of coordinates for the input sequence

        `input_length`: length of original input sequences, I
        `profile_length`: length of profile predictions, O
        `input_center_cut_size`: centered cut size of SHAP scores used
        `profile_center_cut_size`: size to cut profiles to when returning them, P

            profiles for all tasks
    Returns an N x (T or 1) x P x 2 array of true profile counts, an
    N x (T or 1) x P x 2 array of predicted profile probabilities, an N x Q x 4
    array of one-hot seqlet sequences, an N x Q x 4 array of hypothetical seqlet
    importance scores, and an N x 3 object array of seqlet coordinates, where P
    is the profile cut size and Q is the seqlet length. Returned profiles are
    centered at the same center as the seqlets.
    Note that it is important that the seqlet indices match exactly with the indices
    out of the N. This should be the exact sequences in the original SHAP scores.
