In bnbc: Bandwise normalization and batch correction of Hi-C data

Description

Get band matrix from ContactGroup.

Usage

getBandMatrix(cg, band.no=1)

Arguments

cg	A ContactGroup object.
band.no	Integer specifying which matrix band. band.no = 1 retrieves the main diagonal.

Details

A band matrix is a matrix whose columns are the band.no-th off-diagonal of each sample's contact matrix. If there are k samples and matrix band band.no has r entries, then the returned band matrix is of dimension r x k.

Value

A matrix with one column per sample in the ContactGroup and number of rows equal to the length of the matrix band.
