readClfEnv: Parsing a CLF file using Affymetrix Fusion SDK
In affxparser: Affymetrix File Parsing SDK

Description Usage Arguments Value Author(s) See Also

This function parses a CLF file using the Affymetrix Fusion SDK. CLF (chip layout) files contain information associating probe ids with chip x- and y- coordinates.

1	readClfEnv(file, readBody = TRUE)

`file`	`character(1)` providing a path to the CLF file to be input.
`readBody`	`logical(1)` indicating whether the entire file should be parsed (`TRUE`) or only the file header information describing the chips to which the file is relevant.

An environment. The header element is always present; the remainder are present when readBody=TRUE.

`header`	A list with information about the CLF file. The list contains elements described in the CLF file format document referenced below.
`dims`	A length-two integer vector of chip x- and y-coordinates.
`id`	An integer vector of length `prod(dims)` containing probe identifiers.
`x`	An integer vector of length `prod(dims)` containing x-coordinates corresponding to the entries in `id`.
`y`	An integer vector of length `prod(dims)` containing y-coordinates corresponding to the entries in `id`.
