BASHExtended: BASH - Extended Defect Analysis

Description Usage Arguments Details Value Author(s) References See Also Examples

View source: R/BASH.R

Description

Returns a score, which assesses the extent to which the background is changing across the array/strip.

Usage

1
BASHExtended(BLData, array, transFun = logGreenChannelTransform, neighbours = NULL, useLocs = TRUE, E = NULL, E.BG = NULL)

Arguments

BLData

BeadLevelList

array

integer specifying which section/array to analyse

transFun

Function to use to transform data prior to running BASH.

neighbours

A Neighbours matrix. Optional - if left NULL, it will be computed, using default generateNeighbours settings.

useLocs

Logical value, specifiying whether the .locs file (if present) should be used to determine neighbours.

E

Numerical vector - The error image to use. Optional - if left blank, it will be computed, using generateE (with bgfilter = "none", i.e. no background filter applied).

E.BG

Numerical vector - The background error image to use. Optional - if left blank, it will be computed from E, using default BGFilter settings (i.e. method = "median").

Details

BASHExtended assesses the change of background across an array.

The error image used should not be background filtered (as opposed to the error image used in BASHDiffuse). Here, E is the error image

Value

Scalar (Extended defect score)
