MAT (Model-based Analysis of Tiling-array)

Requires Affy CEL files to be in a particular format. Type 4 binary files will not work.

If you get an error message such as: 'not a valide cel file '

By default Command Console exports CEL files in type 4 format. To convert them into the correct format for MAT, use affy power tools. There's a program called: apt-cel-convert which will do the trick. It interconverts the following types:

From a linux command line:

apt-cel-convert -f text -o text-cels *.CEL

I'm not sure how to query the files to see what type they are.
