View source: R/scanBabFile.R

Provides a mechanism to extract the information from the original .locs file from a compressed .bab file, without the need to extract the intensity or probe ID values.

1	extractLocsFile(inputFile, path = ".")

`inputFile`	The name of the .bab file to be read in.
`path`	Path to where the input file can be found. Default is the current working directory.

A matrix with two columns (four if two-channel data) containing the X and Y values of the bead centre coordinates supplied in the original .locs file. For two-channel data the first two columns contain the coordinates from the green channel, with the red channel held in columns three and four.
