def sort_genes(self, inplace=False):
<EOL>self.sort_index(inplace=inplace)<EOL>
Sort the rows of the profile alphabetically by gene name.

        Parameters
        ----------
        inplace: bool, optional
            If set to True, perform the sorting in-place.

        Returns
        -------
        None

        Notes
        -----
        pandas 0.18.0's `Series.sort_index` method does not support the
        ``kind`` keyword, which is needed to select a stable sort algorithm.
