`ancIBD.postprocessing`

Class for calling IBD from Posterior Data. Saves results as tab seperated .tsv created by Pandas and Numpy Contains Sub-Classes, as well as factory Method. Pls always change parameters with set_params method! @ Author: Harald Ringbauer, 2020

Module Contents

Classes

`PostProcessing`	Class that can do PostProcessing of HAPSBURG output.
`NoPostProcessing`	Class that does no Postprocessing
`IBD2Postprocessing`	Class that can do PostProcessing of HAPSBURG output.

Functions

load_Postprocessing([p_model])

Factory Method for PostProcessing class

class ancIBD.postprocessing.PostProcessing(folder='')

Bases: object

Class that can do PostProcessing of HAPSBURG output. (for one individual). Sometimes post-processing is done outside that, Has Methods to save the output. Saves using standard hapROH format
