GCOS should be: 'Gene Chip Operating System',

it is an environment in which you have all the software provided by
Affymetrix in order to:

- manage scanner, fluidic station etc.
- manage, organize and storage all the experiments in a database
- analyze your chip with MAS5 algorithm
- made just a very little bit of data-mining...

GCOS use MAS5 algorithm...
