Description Usage Arguments Value

This function is used to calculate the ABC score based on the the nature spline curves fitted for each branch. ABC score is used to quantify the total magnitude of divergence between two branchs. By default, the ABC score is the area between two fitted spline curves. The ABC score can be used to rank gene divergence. When coupled with p-val calculated from the branchTest, it can be used to identify potential major regulators for branch bifurcation.

`cds` |
a CellDataSet object upon which to perform this operation |

`trend_formula` |
a formula string specifying the full model in differential expression tests (i.e. likelihood ratio tests) for each gene/feature. |

`branch_point` |
the point where two branches diverge |

`trajectory_states` |
States corresponding to two branches |

`relative_expr` |
a logic flag to determine whether or not the relative gene expression should be used |

`stretch` |
a logic flag to determine whether or not each branch should be stretched |

`cores` |
the number of cores to be used while testing each gene for differential expression |

`verbose` |
a logic flag to determine whether or not we should output detailed running information |

`min_expr` |
the lower limit for the expressed gene |

`integer_expression` |
the logic flag to determine whether or not the integer numbers are used for calculating the ABCs. Default is False. |
