[BioC] number of grid columns is not 4 - error

[Morten]

Hello

My name is Morten and I am a newbee. Using R 1.9.1 and limma 1.7.8. I have some 
trouble in getting the layout for a GenePix GAL file supplied from Axon 
Instruments.

> gal <- readGAL()
> layout <- getLayout(gal)
Error in getLayout.default(gal) : number of grid columns is not 4

the final line in my GAL file looks like this:
1	105	215	Pro25G	(+)Pro25G-03	1	pos	Pro25G	NA

Im stuck:(
