CNVScope (version 3.7.2)

rebinGenomicInteractions: Assign GenomicInteractions to a predefined series of bins for row and column, corresponding to a genomic matrix.

Description

This function allows the user to assign a set of genomicinteractions to a pre-existing matrix with known dimensions and column/row names. It finds the row/column index of each point and produces a merged dataframe with the original annotation columns that correspond to each bin in the matrix, with appropriate labels & indexes.

Arguments

gint

A GenomicInteractions object needing to be binned.

whole_genome_matrix

A matrix with underscored positions for column and rownames e.g. chr1_1_5000,chr1_5001_10000. If this is provided, it will override rown/column names and GRanges objects.

rownames_gr

A Genomic Ranges object created from the whole genome matrix row names in chr_start_end format, e.g. chr1_1_5000. No effect if whole_genome_mattrix is specified.

colnames_gr

A Genomic Ranges object created from the whole genome matrix column names in chr_start_end format. No effect if whole_genome_mattrix is specified.

rownames_mat

The row names of the whole_genome_matrix in chr_start_end format.

colnames_mat

The column names of the whole_genome_matrix in chr_start_end format.

method

Method to rebin with-- can use overlap and nearest methods.Default: nearest.
