public abstract static class AffymetrixCelFile
extends AffymetrixFile

An AffymetrixCelFile object represents a single Affymetrix CEL file.

Usage

AffymetrixCelFile(..., cdf=NULL)

Arguments

`...`	Arguments passed to `AromaMicroarrayDataFile`.
`cdf`	An optional `AffymetrixCdfFile` making it possible to override the default CDF file as specified by the CEL file header. The requirement is that its number of cells must match that of the CEL file. If `NULL`, the CDF structure is inferred from the the chip type as specified in the CEL file header.

For developers

If you subclass this class, please make sure to query the AffymetrixCdfFile object (see *getCdf()) whenever querying CDF information. Do not use the CDF file inferred from the chip type in CEL header, unless you really want it to be hardwired that way, otherwise you will break to possibility to override the CDF structure.
