Usage


See wiki for format spec.
https://github.com/blajoie/crane-nature-2015/wiki

$ perl scripts/matrix2insulation.pl

Tool:           matrix2insulation.pl
Version:        1.0.0
Summary:        calculate insulation index (TADs) of supplied matrix

Usage: perl matrix2insulation.pl [OPTIONS] -i <inputMatrix>

Required:

        -i         []         input matrix file

Options:

        -b         []         size (bp) of the insulation square

        -v         []         FLAG, verbose mode

        -ids       []         insulation delta span (size (bp) of insulation delta window)

        -im        []         insulation mode (how to aggregrate signal within insulation square), mean,sum,median

        -nt        [0.1]      noise threshold, minimum depth of valley

        -bmoe      [3]        boundary margin of error (specified in number of BINS), added to each side of the boundary

Notes:
        This script calculates the insulation index of a given matrix to identify TAD boundaries.
        Matrix can be TXT or gzipped TXT.
        See git wiki for details.
