pdInfo2Cdf: Generates an Affymetrix CDF file from a Platform Design (PD) package and a auxillary CEL file for the same chip type
Description
Generates an Affymetrix CDF file from a Platform Design (PD) package and a auxillary CEL file for the same chip type.
Platform Design (PD) packages are also known as "pdInfo" packages. Disclaimer: This is a user-contributed function.
Instead of using this method, we recommend to use
writeCdf()
for the AffyGenePDInfo class.
Usage
pdInfo2Cdf(pdpkg, celfile, overwrite=FALSE, verbose=TRUE, ...)
Arguments
pdpkg
A character string for an existing PD package. celfile
The pathname to an auxillary CEL for the same chip type.
overwrite
If TRUE, an existing CDF is overwritten, otherwise
an exception is thrown. Value
Returns (invisibly) the pathname to CDF written.
The CDF filename is generated from the name of the PD package.
Limitations
The information available in the PD package is limited and does
not contain all information needed to populate a CDF file.
In order to workaround these limitations, certain CDF entries
are set to predefined/hardwired values.
The 'pbase' and 'tbase' entries of the generated CDF file is
hardwired to "T" and "A", respectively. Likewise, the 'groupdirection'
entry is hardwired to "sense".See Also
