In CamaraLab/STvEA: Spatially-resolved Transcriptomics via Epitope Anchoring

Filter anchors, keeping those that are also in the knn of the L2Norm of the original feature space

Description

Filter anchors, keeping those that are also in the knn of the L2Norm of the original feature space

Usage

FilterAnchors(
  ref_mat,
  query_mat,
  anchors,
  k.filter = 200,
  eps = 0,
  verbose = FALSE
)

Arguments

ref_mat	a (cell x feature) protein expression matrix
query_mat	a (cell x feature) protein expression matrix to be corrected
anchors	the list of anchors between matrix1 and matrix2 as output by FindAnchorPairs
k.filter	number of nearest neighbors in original feature space to use for filtering
eps	error bound on the neighbor finding algorithm (from RANN)
verbose	...

Value

a matrix where each row is an anchor pair of cell indices
