get_ambiguous_colocalization: Get ambiguous colocalization events from trait-specific...

In colocboost: Multi-Context Colocalization Analysis for QTL and GWAS Studies

Get ambiguous colocalization events from trait-specific (uncolocalized) effects.

Description

get_ambiguous_colocalization get the colocalization by discarding the weaker colocalization events or colocalized outcomes

Usage

get_ambiguous_colocalization(
  cb_output,
  min_abs_corr_between_ucos = 0.5,
  median_abs_corr_between_ucos = 0.8,
  tol = 1e-09
)

Arguments

cb_output	Output object from colocboost analysis
min_abs_corr_between_ucos	Minimum absolute correlation for variants across two trait-specific (uncolocalized) effects to be considered colocalized. The default is 0.5.
median_abs_corr_between_ucos	Median absolute correlation for variants across two trait-specific (uncolocalized) effects to be considered colocalized. The default is 0.8.
tol	A small, non-negative number specifying the convergence tolerance for checking the overlap of the variables in different sets.

Value

A "colocboost" object of colocboost output with additional elements:

ambiguous_cos

If exists, a list of ambiguous trait-specific (uncolocalized) effects.
