R: Aggregate replicated sample's nucleosomes.

Aggregate replicated sample's nucleosomes.

------------------------------------------

Description

~~~~~~~~~~~

This function aggregates nucleosome for replicated samples. It uses

TemplateFilter ouput of each sample as replicate. Each sample owns a set

of nucleosomes computed using TemplateFilter and ordered by the position

of their center. Adajacent nucleosomes are compared two by two.

Comparison is based on a log likelihood ratio score. The issue of

comparison is adjacents nucleosomes merge or separation. Finally the

function returns a list of clusters and all computed *lod\_scores*. Each

cluster ows an attribute *wp* for "well positionned". This attribute is

set as *TRUE* if the cluster is composed of exactly one nucleosomes of

each sample.

Usage

~~~~~

::

    aggregate_intra_strain_nucs(samples, lod_thres = -20, coord_max = 2e+07)

Arguments

~~~~~~~~~

``samples``

A list of samples. Each sample is a list like *sample = list(id=...,

marker=..., strain=..., roi=..., inputs=..., outputs=...)* with *roi =

list(name=..., begin=..., end=..., chr=..., genome=...)*.

``lod_thres``

Log likelihood ration threshold.

``coord_max``

A too big value to be a coord for a nucleosome lower bound.

Value

~~~~~

Returns a list of clusterized nucleosomes, and all computed lod scores.

This fucntion embed a recursive part. It occurs when a substracted

region split an original region on two.

Usage

~~~~~

::

    substract_region(region1, region2)

Arguments

R: Translate coords of a genome region.

Translate coords of a genome region.

------------------------------------

Description

~~~~~~~~~~~

This function is used in the examples, usualy you have to define your

own translation function and overwrite this one using *unlockBinding*

features. Please, refer to the example.

Usage

~~~~~

::

    translate_roi(roi, strain2, config = NULL, big_roi = NULL)

Arguments

~~~~~~~~~

``roi``

Original genome region of interest.

``strain2``

The strain in wich you want the genome region of interest.

``config``

GLOBAL config variable

``big_roi``

A largest region than roi use to filter c2c if it is needed.

Examples

~~~~~~~~

::

    # Define new translate_roi function...

    translate_roi = function(roi, strain2, config) {

        strain1 = roi$strain_ref

        if (strain1 == strain2) {

            return(roi)

        } else {

          stop("Here is my new translate_roi function...")      

        }   

    }

    # Binding it by uncomment follwing lines.

    # unlockBinding("translate_roi", as.environment("package:nm"))

    # unlockBinding("translate_roi", getNamespace("nm"))

    # assign("translate_roi", translate_roi, "package:nm")

    # assign("translate_roi", translate_roi, getNamespace("nm"))

    # lockBinding("translate_roi", getNamespace("nm"))

    # lockBinding("translate_roi", as.environment("package:nm"))    

R: Aggregate regions that intersect themnselves.

Aggregate regions that intersect themnselves.

---------------------------------------------

Description

~~~~~~~~~~~

This function is based on sort of lower bounds to detect regions that

intersect. We compare lower bound and upper bound of the porevious item.

This function embed a while loop and break break regions list become

stable.

Usage

~~~~~

::

    union_regions(regions)

Arguments

~~~~~~~~~

``regions``

The Regions to be aggregated
