bpmapCluster2Cdf: Creates a CDF from tiling-array BPMAP file

Description

Creates a CDF from tiling-array BPMAP file. NOTE: This method applies only to Affymetrix tiling arrays! Furthermore, it is likely to be more useful for promoter tiling arrays and less so for whole-genome tiling arrays.

Usage

## S3 method for class 'default':
bpmapCluster2Cdf(pathname, chipType, tags=NULL, maxProbeDistance=3000, minNbrOfProbes=30, ..., rows=NULL, cols=NULL, groupName=gsub("_.*", "", chipType), field="fullname", stringRemove=sprintf("%s:.*;", groupName), verbose=-10)

Arguments

pathname
The pathname to the BPMAP file.
chipType, tags
The chip type and optional tags of the CDF to be written.
maxProbeDistance
A positive integer specifying the maximum genomic distance (in basepairs) allowed between two probes in order to "cluster" those two probes into the same CDF units. Whenever the distance
minNbrOfProbes
A positive integer specifying the minimum number of probes required in a CDF unit. If fewer, those probes are dropped.
...
Not used.
rows, cols
Two (optional) positive integers. If NULL, optimal values are inferred auotmatically.
groupName
A character string.
field
A character string.
stringRemove
An (optional) regular expression.
verbose
See Verbose.

Value

  • Returns (invisibly) a the pathname of the created CDF file. The created CDF is written to the current directory.
