## Reading GenePix Gal file

### Description

Reading a standard Gal file containing gene information.

### Usage

    read.Galfile(galfile, path = ".", info.id = c("Name", "ID"),
    labels = "ID", notes = galfile, sep = "\t", skip = NULL, quote = "\"",
    fill=TRUE, ncolumns=4, ...)

### Arguments

`galfile` | a character string representing the Gal file.
