``` |

`ghd_val` |
Generalized Hamming Distance value calculated using topological graphs of g_A and g_B. |

`mu_perm` |
Asymptotic value of mean permutation for graph g_A. |

`p` |
Represents the number of nodes in graph g_A which is the same as number of nodes in graph g_B. |

`matrixA` |
Topological matrix obtained from graph g_A. |

`matrixB` |
Topological matrix obtained from graph g_B. |

`threshold` |
Threshold after which the "fast-approx" technique switches to use a model selection criterion similar to the "original" approach to identify statistically significant changes between two networks. By default its value is 1e-250 and a good range for this value is between 1e-50 to 1e-250. |

A data frame comprising of:

`actual_id` |
Id of a node from the set of nodes in g_A |

`dim_name` |
Name associated with a node from the set of nodes in g_A. |

`p_val` |
P-value associated with that node. |

`ghd_val` |
Generalized Hamming Distance between the topological matrices after removal of that node. |

`mu_perm` |
Asymptotic first order moment: mean value. |

`std_perm` |
Asymptotic second order moment: standard deviation value. |

`V7` |
Adjusted p-value associated with that node. |
